Question

The radius of the driving wheel of an engine is 1.75 how many revolution will it make in travelling 22km

Answer 1

Let's say the radius of the wheel is 1.75 meters,

That will make the circumference of the wheel 2r*pi which equals to 10.996 meters.

Divide the travel distance by the wheels circumference;

22000m/10.996m = 2000.72 revolutions
aprox. to 2001 revolutions
