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.

So the LINEAR speed of the TIP of the minute hand = 2π * 0.05 meter / 3600 sec
         = 0.0000872 meters/sec or 0.08 mm/sec
         = 31.4 cm / hour

The angular speed of the minutes hand is :
         360 degrees / 3600 seconds = 0.1 degree/second
