Question

The diameter of the wheel of a bullock cart is $56$ cm. Find the number to cover a distance of $2.2$ km.

Answer 1

Diameter of the wheel (d) = 56 cm.

Number to cover distance = 2.2 km

radius of the wheel = $\frac{d}{2}=\frac{56}{2}=18cm$

Distance covered by 1 rotation = $\pi d$

$=\frac{22}{7}=10$

$=56.5m$

Means 1 rotation it will move = 56.5 m

so, total distance covered on 2.2 km

2.2 km = 2200 m.

Total distance = 2200/56.5

= 38.9

$\therefore$ The number to cover a distance of 2.2 km

= 39 m
