Question

Angle between the minute hand of a clock and hour hand when the time is 7 : 20 am is :

(A) 80° (B) 100° (C) 120° (D) 90

Answer 1

Hence, when the big needle rotates 120 degree, the small needle rotates by 30/3 = 10 degree

Hence, at 7:20 AM/PM:

The minute needle is at an angle of 120 degree clockwise.

The hour needle is at 210+10=220 degree clockwise.

So, the minimum angle = 220-120=100 degree.
