At what angle are the hands of a clock inclined at 4 hours 20 minutes?
5°
10°
20°
30°
25°
Formula to calculate angle = (11m/2) - 30h
Where, m = minute & h = hour
So, Angle when the time is 4 : 20 = (11 x 20/2) - 30 x 4
= 110 - 120 => -10
Ignore the negative sign,
The angle = 10 degree
Angle = 11/2(min) - 30(h)
= 11/2 (20) - 30(4)
= 110 - 120
= 10 degree
Therefore the correct answer is option no. 2
