Question

A bus is moving with a speed of 65 ½ km per hour. How much distance will it cover in 1$\frac{1}{3}$ hours.

Answer 1

It is given that

Speed of bus = 65 ½ km per hour

We can write it as

= (2 × 65 + 1)/ 2

By further calculation

= (130 + 1)/ 2

= 131/ 2 km

Distance covered in 1$\frac{1}{3}$hour = 4/3 hour can be written as

= 131/2 × 4/3

We get

= 131/1 × 2/3

We know that distance covered = speed × time

= 131/2 × 4/3

= (131 × 2)/ (1 × 3)

So we get

= 262/3

= 87$\frac{1}{3}$ km
