Time to complete one circular revolution is know as time period
it is given by formula
[tex]T = \frac{2\pi}{\omega}[/tex]
here
[tex]\omega = angular speed = 1.52 rad/s[/tex]
now time to complete the revolution is given by above formula
[tex]T = \frac{2\pi}{1.52}[/tex]
[tex]T = 4.13 s[/tex]
So this will complete one revolution in 4.13 s
