Question

A cyclist travels 20 km from home to the park.

She leaves home at 11:10 and arrives at the park at 11:40.
What is her average speed in km/h?

Answer 1

40 kph

Explanation:

I'm not to familiar with km but if it took you 30 minutes to travel 20km you would have to be going 40kph. It's basic math too. If you went 20 kph for 20km it would take you an hour to get there, but since they made it in 30 minutes, you just double the speed.
