The wheel makes 150 rpm. What is the period of rotation of the wheel?

The oscillation period (T) is equal to the ratio of time (t) to the number (number) of oscillations (N).
Because SI time is 1 second, then we translate 1 minute into seconds.
1 minute = 60 seconds
T = 150/60 = 15/6 = 5/2 = 2.5 seconds
