Answer:
25 minutes are gained by minute hand in 60 minutes.
Step-by-step explanation:
Before we actually start solving problems on angles, we need to get couple of basic facts clear:
-Speed of the hour hand The hour hand completes a full circle or 360 degrees in 12 hours or 720 minutes
-Speed of the minute hand The minute hand completes a full circle in 60 minutes
At 'n' o' clock, the angle of the hour hand from the vertical is 30n
The angle between the hour hand and minutes hand
Ф = (30 H - 11 M /2)
H = 5 and angle = 0°
When minute & hour hands coincide, then Ф → = 0
0 = 30 × 5 - 11 M /2
⇒ 0 = 150 - 11 M/ 2
⇒ 150 = 11 M /2
⇒ 300 = 11 M
⇒ M = 300 / 11
⇒ M = 27 (3 / 11 )
∴ 25 minutes are gained by minute hand in 60 minutes.
At 5 o'clock two hands are 25 minutes apart. Therefore in order to coincide the long hand must gain 25 minutes as 55 minutes are gained by minute hand in 60 minutes.
