Question

A cyclist travels 4.9 km in 30 minutes.
What is his average speed in km/h?

Answer 1

9.8 km/h

Explanation:

Since there are 60 minutes in an hour, we can find his speed in km/h by multiplying 4.9 by 2.

4.9(2)

= 9.8

This means that he will travel 9.8 km in 60 minutes (1 hour).

So, his average speed is 9.8 km/h
