The wheel of a bullock cart has a diameter of 1.4 m. How many rotations will the wheel complete as the cart travels 1.1 km ?

Explanation

Let the wheel of the cart complete x rotations.
The distance covered by the wheel = `"the circumference of the wheel" xx "the number of rotations"`
`therefore 1.1 xx 1000=1.4xx22/7xxx`
`therefore x=(1.1xx1000xx7)/(22xx1.4) therefore x=250`
The wheel completes 250 rotations.
