Answer 2

Given,

The speed of the car = 30 m/s

To find,

The speed of the car in kilometres per hour unit.

Solution,

We can easily solve this mathematical problems by using normal arithmetic method.

The speed of the car is,

In 1 second = 30 metres

In 3600 seconds = 30×3600 = 108000 metres

In 1 hour = 108 kilometres

(We successfully converted the given term in the prescribed units.)

Hence, the speed of the car is 108 km/h.
