| How many times is the rotating frequency of the second hand of the watch greater than the rotating frequency of the minute hand? And clockwise?
Clock second hand rotation frequency:
n1 = N1 / t, where N is the number of revolutions of the second hand in 1 hour (N = 3600 revolutions), t is the rotation time of the second hand (t = 1 hour).
Clock minute hand rotation frequency:
n2 = N2 / t, where N is the number of revolutions of the minute hand in 1 hour (N = 60 revolutions).
Clockwise rotation frequency:
n3 = N3 / t, where N is the number of clockwise revolutions per hour (N = 1 revolution).
n1 / n2 = 3600/60 = 60 times.
n1 / n3 = 3600/1 = 3600 times.
