Hansel And Gretel Are Lost In The Woods. How Long Until Hope Is Gone?

1stone for 5 minutes 108 stones for ? 108*5=540 minutes 540/60 (hours) 9 hours

108*5=540 minutes to convert it into hours divide by 60 so answer is 9 hours

1stone forfor 5 minuts 108ston for? 60/5=12; 108/12=9

108 divided by 12

given: 108 stones. in every 5 minutes they drop 1 stone.. solution: 108stone x (5min/1stone.) = 540min. convert min into hrs.. 540min x (1hr/60min) = 9hrs. :)

108*5=540,540/60=9 . This is the ans.

We can view it like this: 1 stone = 5 min. We need to figure out how many minutes 108 stones equal. Just multiply 5 minutes by 108 to get 540, which is the number of minutes that 108 stones are equal to. Then simply divide 540 minutes by 60 minutes to get the number of hours. We then see that Hansel and Gretel have 9 hours worth of stones.

every hour they drop $\frac{60}{5}$ which is 12. $\frac{108}{12}$ is 9

so the answer is 9 hours

1 stone for every 5 min

108 stones for ? min

108x5/1=540

540/60min

9 hours

There are 60 min. in 1hr.

$60/5=12 stones per hour.$

$108/12= \boxed{9hrs}$

1 stone for 5 minutes 12 stones for an hour Totally 108 stone 108/12= 9 hours

1 stone is dropped after 5 minutes so 108 stones will be dropped after 108*5=540 minutes.Converting minutes into hours.1 hour has 60 minutes so 540/60=9 hours.

total time taken will be=108*5=540 minutes

so in hrs it is =to

9 hrs

108 x 5 = 540 which equals to 9 hrs

1stone for 5 minutes 108 stones for ? 108 x 5=540 minutes 540/60 9 hours

for every 5 minutes he dropped 1 stone therefore first we will change minutes to hours 5min.= 5\60 = 1\12hrs. therefore by dividing 108\1\12 we get 9

one Stone for 5 mintes so total stones is 180, he spent 5mintes for one stones so 180*5=540 minutes. it mean's to say 1hour = 60minutes. so 540/60=9hours.

Easy... 1 stone every 5 minutes... therefore, 108 stones in 108X5=540 minutes => 540/60=9 hours

108*5=540/60=9

108*5=540mins then 540/60=9 hours

1 caillou toutes les 5 minutes soit 12 cailloux à l'heure. 108/12=9

All right !

108 stones divided by 12 (5 minute sequences in an hour) equals 9 hours.

since a stone dropped every 5 minutes so we have to multiply no of stones by 5 to get the no of minutes required for dropping all stones 108*5 =540 minutes since one hour = 60 min 540/60 = 9 hours

since they drop one stone every 5 min and they have 108 stones so we multiply the number of stones (108) by number of minutes (5) the result will be 540 minutes as one hour contain 60 minutes we divide 540 by 60 the result will be 9 hours

5*108/60

1 white stone in every 5 minutes, so we have 12 5minutes in One hour hence, 108 divided by 12= 9 ... so 9 hours before they lost all the small white stone

12 stones for each 1 hour .so 108 stones in 9 hours.

in 1 hour , 12 stones will be dropped , 1 stone in every 5 minutes so 108 /12 = 9 hours

108*5=540/60=9

1 stone dropped in 5 min. So, in 1hr i.e 60 min stones that will be dropped= 60/5 i.e 12 stones So , 108/12=9hrs hence, 108 stones will be dropped in 9 hrs

1 stone dropped after = 5 minutes

108 stones dropped after = 108 * 5 minutes = 540 minutes = 540/60 = _9 Hours _

108*5=540 540/60=9

1 stone drops every 5 mins.;there are 108 stone(whte stones) 5x108=540 mins. ===>>> 540mins/60 mins (60mins=1hr) =9hrs.

<1 Stone every 5 minutes.And they are asking for hours so, 60/5="12"> 108 dived by 12 is 9. Then the answer is 9 HOURS

they drop one stone in every 5 min. thus, 108*5=540 min. now, 540/60[min. in one hour]=9 hrs. answer is 9 hrs.

There are 108 stones and each stone is fell after 5 minutes. So, total amount of time till which stones can be fell : 5(108) = 540 Then , Divide 540 and 60 (1hours=60 mins ) Is equal to 9

Since Hansel and Gretel drop 1 stone every 5 minutes, you multiply 108 by 5. Answer is 540 minutes. To find out how many hours, you divide 540 minutes by 60 minutes, the answer is 9 hours.

in 1 hour = 12 stones 108 stones divided by 12 stones = 9 hours

A simple problem. All you need to find 1st is the number of minutes the stones can last, ie, 5 x 108= 540. 540/60=9. Thats the answer!

1 stone/min = 12 stone/hr = 108 stone/ 9hrs

They drop 1 white stone per 5 min . so for 1 hour they drop 12 stones . the total number of stones they have is 108. to get the hour travelled by them we have to divide. to divide: total number of stones and the stones dropped per hour = 108/12 = 9.

There are $108$ stones and each stone is fell after $5$ minutes.

So, total amount of time till which stones can be fell $=5\times 108 = \boxed{540\text{ minutes }}$

Now, if we convert this time into hours, we have Total time $=\frac{540}{60}=\boxed{9\text{ hrs }}$

60 minutes / 5 minutes per stone drop = 12 stones per hour dropped.

108 stones total/ 12 stones dropped per hour = 9 hours to run out of stones.

108*5=540 then 540/60 or you can cancel done to 54/6=9

One stone for every 5 min. I.e. Minutes = no. Of stone * time for dropping the stone. Minutes = 108*5 = 540. In hours, the time is 540min / 60 = 9 hours

One stone is dropped every 5 minutes and there are 108 stones. SO total number of minutes they can walk throwing stones = 5*108=540 minutes which when converted in hours by dividing by 60 we get 9 as the answer :)

no. of stones=108 time interval=5 min time taken=108*5=540min=9 hrs

5x108 = 540 Minutes 540/60 = 9 Hours

(108x5) / 60 = 9
