Question

Find the angle of a minute hand of wall clock in 2hr 20 min

Answer 1

Answer:

Angle covered by the hour hand in 1 minute = (1/2)°. Thus, at 2 hrs 20 min past 12, X = 140 x ½ ° = 70°. Thus, angle between hour and minute hand at 2 : 20 hrs= 120° - 70° = 50°.

Answer 2

Angle covered by the hour hand in 1 min = (1/2)°

thus at 2 hours 20 min past 12,X=140x1/2=70°

thus angle between hour hand and min hand at 2 :20 hrs =120°- 70°=50°
