The diameter of wheel is 0.70 m. Find the distance covered by it in 500 revolutions.

If the wheel takes 5 min. to make 500 revolution, find its speed in:

i) m/sec

ii) km/hr

Solution

1 revolution =circumference
=2(22/7)(7/20)=2.2
Distance covered=500*2.2=1100
Time=5min=300 sec
Speed=11/3 m/sec
Distance =11/10 km
Time=1/12
Speed=12/10=1.2 km/hr
