Question

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

Answer 1

`$\underline{\bold{Your\: Answer }}$`

Diameter of wheel=1.4 m
1 rotation=Its circumference

Circumference=πd
=22/7×1.4
=22×0.2
=4.4 m

Means in 1 rotation
It will move=4.4 m

So total rotation on 1.1 km
1.1 km=1100 m

Total Rotation=1100/4.4=250

Total Rotation ➡️250

Answer 2

distance covered by wheel in one rotation
=pie d=22÷7×1.4=4.4 m
rotation cover=1100m
r= 1100÷44×10
r= 250 m.
240 rotations were made.
