Step-by-step explanation:
The distance that a wheel travels in one rotation is simply the circumference of the circle.
Circumference of wheel= 2* pi* radius.
2* (22/7)*14= 88 cm
So wheel can travel 88 cm in 1 rotation.
And it has to cover 2200m(220000cm)
So 220000/88=2500
So wheel rotates 2500 times to travel 2km 200m
