Greay where did you fnd it ?? Google ?
360/12=30 4*30=120
first, to solve this question we should know how many degrees that is made in 1 minutes
a 12 hour analogue clock is consist of 12 number that usually have a circle shape, in one circle there are 360 degree and in one circle of the clock there are 60 minutes. so, in 1 minutes there are 6 0 m i n u t e s = 3 6 0 d e g r e e s 1 m i n u t e s = 6 0 3 6 0 d e g r e e s 1 m i n u t e s = 6 d e g r e e s
now, after get there are 6 degrees that is made in 1 minutes, let search how many degrees that is made in 20 minutes 2 0 m i n u t e s = 6 × 2 0 d e g r e e s 2 0 m i n u t e s = 1 2 0 d e g r e e s
therefore, in 20 minutes there are 120 degree
Every 5 minutes, the minute hand travels 30 degrees. For 20 minutes, the minute hand would travel 120 degrees.
The minute hand does the complete 360° rotation in 1 hr(60 min)
So, in 1 min, the minute hand rotates = ( 6 0 3 6 0 ) ° = 6 °
Then, in 20 min, the minute hand rotates = ( 2 0 × 6 ) ° = 1 2 0 °

@Kushagra Sahni – Yes, my parents told me that they are gonna cut off my PC during my class 12 and i'm starting to prepare for class 12 from tomorrow, i guess, so i won't be much active on Brilliant. Gonna start early preparation for the 12th Boards.....

@Prasun Biswas – All the best for your preparations. I am sure that you will do well in your exams as you are starting very early and are a good student. Good luck. Hope to see you soon.
60 minutes 360 degree 20 min = 360/60*20 = 120 degree
Note that 5 m i n u t e s = 3 0 ∘ . Therefore by ratio and proportion, we have
2 0 x = 5 3 0
x = 5 2 0 ( 3 0 ) = 1 2 0
in one minute the hand moves 30 degree
so in 4 subdivisions it will move 120 degree
aliter 4(x)+2(x)=180
(x)=30
4(x)=20 minutes moves 120 degree .
Clock is a circle and has 60 minutes total time. Suppose the big needle started from 12 and completed 20 minutes then it will reach at 4, then the angle can be found out by 20/60 *360 degrees = 120 degrees.
clock hands revolve around a center in a circle =360 degrees 20 min=1/3 hrs so 360 .*1/3= 120 degrees
In 60 min the minute hand covers 360 degree
so in 1 min the minute hand covers 6 degree
therefore in 20 min the min hand covers 120 degree
One whole revolution is equal to 3 6 0 ∘ .
Divide it by the number of minutes an hour has ( 6 0 m i n u t e s 3 6 0 ∘ ) and we have 6 m i n u t e ∘ .
Multiply 6 with 2 0 (the given) and their product is 1 2 0 ∘
20 is 1/3 of an hour. One hour= full circle= 360 degrees. If you divide 360 by 3, you get your answer of 120.
There are two ways i came up with to solve this one way is to figure out how many degrees are in the clock for every minute which is 6 (360 deg.= 60min)/60=6 deg/m. Then since the question is questioning for 20 minutes the answer would be 120 degrees.
in every min there is movement of 6 degree then multiply 20 into 6
at 3 oclock... the hand of the clock is at 90 degrees from 12 o'clock... its appears to have 3 divisions between 3 to 12... so 90 degrees divide by 3 is 30... if 3 o'clock from 12 oclock is 90 degrees at 15 minutes in the minute hand... plus one division to reach 4 oclock... we have 90 degrees plus 30 is 120
Total number of degrees around a point are 3 6 0 ° . And number of minutes in an hour are 6 0 . So we have, 6 0 3 6 0 ° = 6 ° . So number of degrees covered by the minute-hand in a minute is 6 ° . Therefore degrees covered in 2 0 minutes is 1 2 0 ° .
1hr=360degrees so 1mint=6degrees 6*20=120
Not 1 hr =360 degrees, it is 12 hours =360 degrees, 1 hour =30 degree, 5 minutes=30 degree, 1 minute =6 degree, 20 minutes =120 degrees.
IN A MINUTE THE MINUTE HAND TRAVELS 360/60=6 DEGREES. SO IN 20 MINUTES IT WILL COVER 20*6=120DEGREES
In One Hour There Are 60 Minutes So For 60 Minutes The Minute Hand Travels 360 Degree Which Implies 6 Degrees For Every Minute.............So For 20 Minutes Times 6=120 Degrees
Minute-hand completes 1 round in 60 min., i.e. 360 degrees.
60 min.= 360 degrees 20 min.= [(360/60) x 20] = 120 degrees (answer).
Degrees of a circle is 360 degrees
It's 60 minutes.
Degrees = 20/60 * 360 = 120 degrees

15 mins would be 90 degrees. 1/3 of 90 degrees(5 mins) is 30 degrees so 30+90 =120
If a circle of 12-hour analogue clock had degrees 360, so every 1 hour have 30 degress ( 360 / 12). From number 12 - 4 have difference 4. So the degrees is 4 x 30 degrees = 120 degrees. Answer : 120
A cada minuto o ponteiro dos minutos aumenta em 6 graus, então em 20*6= 120 graus

So, a clock is obviously a circle, which is 360 degrees. We want to find how many degrees a clock covers in one minute: 360 degrees/60 minutes for the minute hand to go around the clock. We will then get 6 degrees per minute. Now we just multiply 6 by the number of minutes passed: 6*20 = 120 degrees in 20 minutes.
