Answer:
25 times.you can try it this following way.
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 22 metres (2200 cm)
So 2200/88=25
So wheel rotates 25 times to travel 22 meters.
