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°.

The perfect formula is 1/2|(60H - 11M)|.

Apply simple formula |11/2 * min - 30 * hr|.

In explanation, why 360/12 and 360/60 are taken?

The shortcut formula to find angle b/w two hands.
1/2[60H - 11M] where H is hour, M min.
If result is above 180 then subtract the answer from 360.
1/2[60H - 11M] where H is hour, M min.
If result is above 180 then subtract the answer from 360.

Direct formula:
|[{(11* Minute) ÷2}-30 * Hour]|
Best accurate formula for finding angle between minutes and hours, coincidence angle, straight line, perpendicular angle and random angle.

11/2m-30hr formula is correct for every angle. And another thing ANGLE IN CLOCKWISE DIRECTION IS NEGATIVE.

SIMPLE FORMULA.
30*H - (11/2)*M
Where, 'H' FOR 'HOUR'; 'M' FOR 'MINUTE'.
Answer will generated in degree angle.
Note:- Suppose, answer of angle is greater than 180 degrees then answer will be reduced or minus (- 360) from original angle for example
1) 3:40 hr.
According to formula,
30*3 - (11/2)*40.
= 90-220
= -130
= 130 degree (and take it +Ve).
30*H - (11/2)*M
Where, 'H' FOR 'HOUR'; 'M' FOR 'MINUTE'.
