Question

An accurate clock shows 8 o'clock in the morning. Through how may degrees will the hour hand rotate when the clock shows 2 o'clock in the afternoon?
a)144º
b)150º
c)168º
d)180º

Answer 1

we have 360°=60 min
    so 1min = 6°
so mins passed by min hand = 30 min
so 30 min =  180°
so answer is d)180°

Answer 2

the angle between 1 hour is 30 degree 
so for 8-2 there r 6 hours
so total degree covered = 30X6=180
