Question

The top speed of a car is 54 metres per second.

Change this speed to kilometres per hour.

Answer 1

To convert metres per second to kilometres per hour, we need to multiply by 3.6 since there are 3600 seconds in an hour and 1000 metres in a kilometer.

54 metres per second * 3.6 = 194.4 kilometres per hour

Therefore, the top speed of the car is 194.4 kilometres per hour.
