Question

the minute hand of a watch is 3cm long. how far does its tip move in 25 mins

Answer 1

Answer:

Hi ! For one complete revolution around the clock, the minute hand takes 60mins OR 360 degrees in 60 mins; thus, speed of the minute hand = 360/60 = 6 degrees per min. Now, in 25 minutes, the minute hand would rotate by => 25 x 6 = 150 degrees.
