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°.

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

What do we do if we have a reverse question?
At what time between 3 and 4 clock will there be 36 degree?

Its simple. Just remember for hour hand it covers 0.5 degree in one minute. And minute hand covers 6 degrees.

Please tell me how makes formula 11m -60H/2?

@Greeshma.
Angle between 2 hands at 6:00.
MIN (M) = 0.
HOUR (H) = 6.
Formula is (|11M-60H|) /2.
So, {|11(0)-60(6)|}/2 = 180.
That's it :-).

It is correct 11/2(20)-30(4) = 110-120 = 10.

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.
