Dan's slowing watch

$1~\text{day}=24~\text{hours}=(24\times 60)~\text{minutes}=1440~\text{minutes}$

$~\text{Hence, he loses}:~\dfrac{1440\times 20}{12}~\text{seconds}=2400~\text{seconds}$

$2400~\text{seconds}=\dfrac{2400}{60}~\text{minutes}=\boxed{40}~\text{minutes}$

hello my name is Harris...please vote my ans. if the watch losses 20 sec in 12 min so it will lose, 100 sec in 1 hour . if it losses 100 sec in 1 hour so it will lose 2400 sec in 24 hour (a day) . now divide 2400 with 60 ( to convert sec in min). 2400/60 = $\boxed{40}$ 40 min . ans thanks.

If Dan loses 20 seconds every 12 minutes ,

then he loses x seconds every 24 hours .

Cross-multiply, we have

x sexonds = $\frac{24 hours * 20 seconds}{12 minutes}$

Adjust the units,

x seconds = $\frac{24 * 60 minutes * 20 seconds}{12 minutes}$

x seconds = 2 * 60 * 20 seconds

In minutes,

x minutes = $\frac{2 * 60 * 20}{60}$

x minutes = 40 minutes

That's the result.

20 seconds per 12 min = 100 seconds per 60 min (1 hour) 100 seconds per hour = 2400 seconds per 24 hours (1 day) = 40 minutes

In 12 min, watch loses 20 sec.

In 1 min, watch loses (20/12) sec.

In 1 hr(60 min),watch loses (20/12)*60 = 100 sec.

So, in 1 day(24 hrs), watch loses (100*24) = 2400 sec = (2400/60) min = 40 min

For every 12 minutes, 20 seconds are lost. In 1 hour, 100 seconds are lost. In 24 hours, 2400 seconds are lost. In minutes, this is $2400/60=\boxed{40}$ minutes lost.

In one hour every 12 minutes watch loses 20 seconds so in one hour: 60/12=5,
5 multiply 20=100 seconds & in 24 hours: 100 multiply 24=2400 , 2400/60=40 minutes

60 min / 12min = 5 5x20s = 100s 100s = 60min or 1 hour 100s x 24 hour = 2400s 2400s / 60 = 40

One day have 1440 Minutes (1 hour - 60 minutes -> 24 hours - x minutes). So, you divide the 1440 minute by 12 minutes. You have a total of 120 minutes. Then, you multiply the valor by 20 seconds (because is 20 seconds about 12 minutes). Then, you have 2400 seconds, so, you divide by 60 seconds, and you have a total of 40 minutes.

1 day = 1440 minutes

1440 minutes/12 minutes = 120 120 * 20 = 2400 second = 40 minutes

1 hour= 60 minutes. then 24 hours= 1440 minutes. Then the watch lose (1440/12)*20 seconds. Then transform it into minutes and the result will be 40.

In 1 minute there are 12 5=60 min so time lost in 1hr=20 5=100sec in 1 day=24*100=2400sec=2400/60=40min

every 12 minutes it loses 20 seconds, then -> 60/12 = 5. -> 5 x 20 = 100 ( loses 100 seconds every hour) -> 24 x 100 = 2,400 seconds per day -> 2,400 / 60 = 40 minutes per day

total minutes in a day - 24x60= 1440 mins By unitary method seconds loss in 20 minutes = 12 seconds loss in 1 minute = 1x12/20 seconds loss in 1440 minutes = 1440x12/20 = 2400 seconds

2400 seconds = 2400/60 mins = 40 minutes

O primeiro passo deverá ser descobrir o número de vezes em um dia que se perde 20 segundos, para isso, sabemos que um dia tem 24 horas e cada hora são 60 minutos, totalizando 1440 minutos em um dia. Assim, 1440 dividido por 12, que é o período em que há uma perda de 20 segundos, obtemos a quantidade total de eventos transcorridos, que totaliza 120 vezes. Em uma vez, perde-se 20 segundos, em 120 vezes, a perda é de 2400 segundos, equivalendo a um tempo de 40 minutos em um dia.

A day is equal to 1440 minutes. and the watch will lose 20 seconds every 12 minutes. (20 s / 12 mins)

So, in a day, the watch will lose 20 seconds for 120 times (1440/12 = 120)

multiple it 20 x 120 = 2400 seconds

but the question ask how many minutes, so 2400 divided by 60 as 1 minute equal to 60 seconds.. and you'll get 40 minutes.

24 hours a day 1440 mins a day 86400 sec a day

Every hour you will loss 100 sec which gives the equation of (lossSec = (60 / 12 ) * 20 ) Every day you will loss 2400 sec which gives the equation of (lossSecDay = lossSec * 24); Convert 2400sec to min which gives the equation of 2400/60 = 40mins

First, let's point some things. 1 min. = 60 s. 1 day = 24(h).60(mins) = 1440 mins.

Now what we have to know is: how many times 12 mins fits in 1440. 1440/12 = 120.

Multiply 20(s) by 120(mins) to find out how many seconds the clock has lost in one day: 120.20 = 2400(s)

Last but not least, convert seconds to minutes by dividing 2400 by 60: 2400/60 = 40.

1 min = 60 sec 12 min = 720 sec 5 12 = 60 min / 1 hour 20 5 = 100 sec / 1:40 min 1*24 = 24 hour 100 *24 = 2400 sec ~ 40 min

A day has 24x60 = 1440 mins . x = 1440 x 20 : 12 = 2400 seconds = 40 mins

24 60 60=86400 86400*20=1728000/720=2400 2400/60=40.

Write a solution.1day =24hours 24x60=1440 minutes then we know that he loses 20 seconds every 12 minutes first we will multiply 20 x 1440=28800 now divide 28800/12= 2400 seconds

but we want answer in minutes

so, 1 minute =60 seconds then , divide 2400/60=40 minutes is the answer

THANK YOU :) :) HAVE NICE DAY

no of seconds lost per 12 minutes = 20 1 hour = 60 mins = 12 x 5 mins no of seconds lost per hour = 5 x 20 = 100 seconds now no of hours per day = 24 no of seconds lost per day = 24 x 100 = 2400 no of minutes lost per day = 2400/60 = 40. therefore no of lost minutes per day = 40

It loses 20 sec. ------> 12 min.

it loses X sec. -------> 1 day(24 x 60)

by cross multiplication: X = (20 x 24 x 60) / 12 = 2400 sec (divide by 60)

X = 40 min

there are 1440 minutes a day

simply divide 1440 to 12 (to get how many 12minutes in 1 day)

1440/12=120

multiply 120 to 20 (to get how many seconds he lose in 1 day)

120x20=2400

since the problem asked how many minutes he lose in one day..

convert 2400 secs in minutes

and we get 2400/60 =40..

so answer will be 40

we have 60 minutes in an hour, times 24 because we 24 hours in a day.
60×24≡1440 then the watch stops every 12 minutes, so it will be divide by 12. 1440÷12≡120 multiplied by 20 because it stops for 20 seconds 120×20≡2400 the answer 2400 is expressed in seconds, so, in able for us to express it in minute we have to divide it by 60 2400÷60≡40 we now have 40 minutes

loses 20 seconds in every 12 minutes so, Dan loses 100 seconds in one hour.. there are 24 hours in a day so, 100 seconds multiply 24..Dan loses 2400 seconds in one day then there are 60 seconds in one minutes.. 2400/60 = 40 minutes. therefore, Dan loses 40 minutes in one day.

1 day = 24 hours and 24 hours =1440 mins... So 1440 / 12= 120 mins.. Now..120*20=2400 sec 2400/60=40 mins ...Ans

1 day =1440 minutes so the actual loss of secs. is =(1440*20/12)=2400 secs. then, in minutes that will be=2400/60=40 minutes

In 12 min 1s 20sec will be loosing. So in a day it looses (24 * 60 ) /12 times. = 120 times a day. . As it looses 20 sec in every 12 min, 120 * 20 / 60 = 40 min a day

1 day = 24 hours = 24*60= 1440 minutes.

In 12 minutes, watch loses 20 second.

In 1 minute, watch loses 20/12 seconds.

in 1440 minutes, watch loses (20/12)*1440= 2400 seconds.

2400 seconds= 2400/60= 40 minutes.

firstly convert 20sec into hr= 20/3600= 0.00555 then convert 12min into hr= 12/60= .2, then 0.00555/.2 into 24= .666hr hence, convert it into min, 0.666 into 60= 39.96 or 40

20 seconds in 12 minutes. 100 seconds in 60 minutes or 1 hour.[multiplying by 5 in both sides]. 2400 seconds in 24 hours (as 24 hours= 1 day) .

As it asked how many "minutes" will the watch lose in a day, we will divide 2400 seconds by 60 (as 60 seconds = 1 minute).

And the answer comes 40 minutes.

1/3 min loss per 12 min; ? min loss per 24*60 min; therefore,one day loss =40 min

24hours x 60 mins = 1440 1440/12 = 120 120x20 = 2400 seconds 2400/60 = 40 minutes!

*shortcut 24/12x20=40minutes

there r 24 hrs in a day & 60 mins in an hour 24 * 60 =1440 mins accordng to the prblem 1440/12 = 120 if watch loses 20 secs every 12 mins , secs lost in a day = 120 * 20 = 2400 secs . mins lost = 2400 / 60 = 40 mins

24 60=1440 <=>1440/12=120 <=>120 20=2400 <=>2400/60=40

12•5 = the number of minutes in an hour (60), so we should multiply the number of seconds lost in 12 minutes, 20 • 5 = 100, to receive the number of seconds lost per hour. 100•24 = 2400, which is the number of seconds lost per day, which divided by 60 (the number of seconds per minute), gives the number of minutes lost per day = 40.

loses 20 seconds in every 12 minutes.

If 1 day = 1440 minutes, means that 20 seconds will be loss for 12 times.

So 12 * 20= 2400 seconds = 40 minutes..

24hr x 60min/1hr = 1440min 1440min/12min = 120 20sec = 1/3 min 120 x 1/3 min = 40 minutes

loses 20 sec. for every 12 min. that implies loses 2400 sec. for a day(24h*60min.) i.e. 40 min.

(20/12) 60 (24)

here, the watch loses 20 sec every 12 min 1 day = 24 hours = 24 x 60 min = 1440 min Now, 1440/12 = 120min i.e. there are 120 12min in 1day So, the total amount of lost seconds is 20 x 120 = 2400 sec Since, the time is asked in seconds 1 min = 60 sec or, 2400 / 60 min =40 min that gives you the answer But, if you are more familiar with the propotion way Then, 12 min = 720 sec & 1 day = 24 hrs = 1440 min = 86400 sec Now, using the ratio, 720 : 20 : : 86400 : y or, 720 / 20 = 86400 / y or, 36 =86400 / y By cross multiplication, 36y = 86400 or, y = 86400 / 36 or, y = 2400 But that is NOT the answer The units of the ratios are same, So it is 2400 sec NOT minutes Then, convert it to minutes by dividing by 60 It will give you 40 minutes

There are 24*60=1440 minutes a day. Dan's watch loses 20 seconds 1440/12=120 times a day, totalling 2400 seconds, or 40 minutes.

20 seconds in 12 minutes means 100 seconds in an hour. so in 24 hours, 100*24=2400 seconds are lost. which becomes 2400/60=40 minutes :-)

12 mins = 720 secs. 1 min = 60 secs. 1 day = 24 hours = 1440 mins = 86400 secs.

In 720 secs the watch loses = 20 secs In 60 secs the watch loses = 20/720 = 0.0277 secs In 86,400 secs the watch loses = 0.02777*86400 = 2400

The watch loses 2400 SECONDS in one day. Converting this value into mins by divinding it with 60. 2400/60 = 40 Mins.

So the watch loses 40 MINUTES in ONE day.

20 seconds per 12 min, so total 20x5x24 seconds for day

as we need the answer in minutes 20x5x24/60 = 40

For 12 min loses 20 s, so for 60 min it loses 100 s. Now 1day= 24 * 60 min, so required loses = 2400 s or 40 min
