Question

It took Alex 2.5 hours to cover a certain route walking at a rate of 3.6 km/h. How long would it take Alex to cover the same route walking at 4.5 km/h?

Answer 1

2 hours

Explanation:

3.6km/h x 2.5 hours was 9km, so 9km divided by 4.5km/h is 2 hours.

Answer 2

It will take Alex 2 hours walking the same route at 4.5 km/h because 3.6km/h times 2.5 hours was 9km, so 9km divided by 4.5km/h is 2 hours.
