The acute angle between the hour hand and minute hand of a clock at 4 PM
IS NOT 1200. (it is 120 degree)
the answer is 120
explanation- the total angle subtended after one rotation =360
total minutes in an hour =60
angle in one minute =360/60=6
at 4 pm hour hand is at 4 and minute hand at 12 so difference between hour and minute hand is 20 minutes
so angle =20 x 6=120
