A wheel is rotating at an angular velocity of 1.2 pi radians/second
while a point on the circumference of the wheel travels at 9.6 pi m in 10 seconds.
a) How many revolutions does the wheel make in 1 minute?

one rev. is 2pi rad.s

so rev.s/min = rad.s /sec * rev.s /rad. * sec/min
                        =( 1.2pi )* (1/2pi)*(60)
