At what angle the hands of a clock are inclined at 15 minutes past 5?
Answer: Option
Explanation:
| Angle traced by hour hand in | 21 | hrs = |  |
360 | x | 21 |  |
° | = | 157 | 1 | ° |
| 4 | 12 | 4 | 2 |
| Angle traced by min. hand in 15 min. = | |
360 | x 15 | |
° | = 90°. |
| 60 |
 Required angle = |
|
157 | 1 | |
° | - 90° = 67 | 1 | ° |
| 2 | 2 |

It is 5:15.
we can assume 15 as "3".
So 5-3 = 2*30+15/2= 60+7.5.
Answer= 67.5.

I think (30*Hrs)-(11/2)*Mins is the correct formula for getting this answer.

Use the formula.
=(11/2*min-30*hour),
11/2*15-30*5,
165/2-150,
135/2=67.5.
=(11/2*min-30*hour),
11/2*15-30*5,
165/2-150,
135/2=67.5.

11/2 *m -30*h.
= 11/2*15 -30 * 5.
= 165/2 -150,
= 82.5-150,
= 67.5.
= 11/2*15 -30 * 5.
= 165/2 -150,
= 82.5-150,
= 67.5.

Best way to find the angle between hr and min hand is 30H - 5.5M.

21/4 = 5 hr 15 min = 5(15/60) = 5(1/4) = ((5*4)+1)/4 = 21/4.

Angle between them 1 hour is 30 degree so 30+30+30/4=67.5.

@ rekha
5 hrs and 15 min so
5+15/60=5+1/4
20+1/4=21/4
5 hrs and 15 min so
5+15/60=5+1/4
20+1/4=21/4

We can use the formula
Theta= (11(Minutes)/2)-30(Hour)
Theta= (11(Minutes)/2)-30(Hour)

21/4=5.25
0.25 is 1/4 part of 60min. i.e. 15min
0.25 is 1/4 part of 60min. i.e. 15min
