Question

A bus has wheels of diameter 1.4m.Travelling from one town to other,the wheels complete 20000 rotations.Find the distance covered by bus.

Answer 1

Answer:

Step-by-step explanation:

Hope this helps.

Let the total distance covered by the bus be x metres.

d = 1.4 m . So r = 0.7 m

Now ,

No. of revolutions = total distance / the circumference of the wheel.

C = 2πr

= 2×22/7×0.7 = 4.4 m

Now,

20000 = x / 4.4

x = 4.4 × 20000 = 88000 m

Thus , the total distance covered by the bus is 88000 metres.
