The answer solving goes like this :
Hr hand rotation per hour = 30°
In general we have
speed of Hr hand = 0.5 dpm (degrees per min)
Converting dpm to dph(degrees per hour):
1 dpm = 60 dph
0.5 dpm = 0.5×60(= 30 dph) which is same as data given in question.
•°• Hr hand speed in 8 days= 8× 24 × (speed of Hr hand in dph)
= 8×24× 30
= 5760 dph
