A wheel of perimetre 220cm rolls ona level road at a speed of 9 km per hr.how many revolutions does..

Answer / mani mohan

perimeter of wheel is nothing but its circumference.when
you streach it the length or distance is going to be 220cm
or 2.2m.the speed is 9 km per hr or 9000 m/360 sec(25
m/sec).so for a second the wheel has to travel 25 m, but
the wheel circumference is 2.2m, so the rps of the wheel is
(25/2.2) 11.36 revolution per second.
