The end of the arrow of the hand rotates in a circle of radius 5 cm. It moves the circumference = 2 π 5 cm in one rotation, that is 60 minutes = 3600 seconds.
Answer:
The minute hand traces its path around the clock once in an hour. The distance travelled by the tip of the hand in this time is 2 x pi x 5cm.
The speed is then 10pi cm/hour, which is 8.73 x 10-5 ms-1.
