Question

19. find the angle between the hour and the minute hand of a clock when the time is 3.25.

Answer 1

An hour hand covers 360° in 12hrs
So it will cover 30° in 1hr
360÷12=30

A minute hand covers 360° in 60mins
So it will cover 6° in 1min
360÷60=6

At 3 the angle covered by hour hand is 90°
and the angle covered by minute hand at 25 mins is 25×6=150

So 150-90=40
Hence the angle between the hour hand and minute hand of a clock evyen time is 3.25 is 40°
