What is the speed of hour hand in a clock?

Answer 1

Elena Albarran

#pi/360# per minute

Hour hand completes a full circle inn #12# hours or #720# minutes

i.e. an angle of #2pi# in #720# minutes

or #(2pi)/720# per minute

or #pi/360# per minute

The speed of the hour hand in a clock is equal to 1/12 of the circumference of the clock face per hour. Since the circumference of the clock face is 12 times the length of the hour hand, the speed of the hour hand is 1/12 of 12 times the length of the hour hand, which simplifies to the length of the hour hand per hour. Therefore, the speed of the hour hand in a clock is the same as the length of the hour hand.
