The angle between the minute hand and the hour hand of a clock when the time is 4.20, is:
Answer: Option
Explanation:
| Angle traced by hour hand in | 13 | hrs = |  |
360 | x | 13 |  |
° | = 130°. |
| 3 | 12 | 3 |
| Angle traced by min. hand in 20 min. = | |
360 | x 20 | |
° | = 120°. |
| 60 |
Required angle = (130 - 120)° = 10°.

12h - 360 degree.
12*60 min --> 360 degree.
1 min -- > 360/12*60.
20 min --> 20*360/(12*60).
-->10 degree.
12*60 min --> 360 degree.
1 min -- > 360/12*60.
20 min --> 20*360/(12*60).
-->10 degree.

Why we are substracting angle traced by hour hand and angle traced by minute hand ?
One another thing is that - if we see the clock at 4.20 hour hand is at 4 and minute hand is also at 4. So angle between them must be 0 degree.
Please clear me.

Direct formula:
|11M-60H|/2
where M=minute, H=hour hands.
|11M-60H|/2
where M=minute, H=hour hands.

Hi girls ! we can write 4.20 also as 13/3, we covert 20 min into hrs 20/60=1/3 and we add with4 hrs 4+1/3=13/3.
Have a nice day.
Have a nice day.

In first can we take 12/3 instead of 13/3 ?

Apply the formula suggested by Reddilavan..
ie: Angle = 30Hr-(11/2)Min
ie: Angle = 30Hr-(11/2)Min

we can convert it in hours as:
20min.=1/3hours
so total hours as 4+1/3=13/3
20min.=1/3hours
so total hours as 4+1/3=13/3

angle=(11/2)*min-30*hrs
apply this formula you can get the answer ......

Hi All,
We can write 4 hrs. 20 mins. as 13/3 hrs.
13/3 = 4 and (1/3)hrs
= 4.20 ( Here 1 hour = 60 mins, 1/3 of 60 is equal to 20).
Hope you understand guys. Have a nice day!
