55. Find the angle between the hour and the minute hand of a clock when the time is 3.25.
A. 47 ½ B. 49 ½
C. 55 ½ D. 57 ½
Answer:
Angle traced by the hour hand in 12 hours = 360°.
Angle traced by it in 3 hrs 25 min = 41 / 12 hrs
= (360 / 12 x 41 / 12)°
= 102 ½°.
Angle traced by minute hand in 60 min = 360°.
Angle traced by it in 25 min. = (360/ 60 x 25)°
= 150°
Required angle = (150- 102 ½°)
= 47 ½°.
