The ratio of the angular velocity of the hour hand, minute hand and second hand

The ratio of the angular velocity of the hour hand, minute hand and second hand

The angular velocity is equal to the angle (2pi) corresponding to one revolution of the pointer on the dial divided by the time of one revolution
W [hour hand]: w [minute hand]: w [second hand] = (1 / 12): (1 / 1): [1 / (1 / 60)] = (1 / 12): 1:60 = 1:12:720
