Question

A cyclist travels 10 km from home to the park.

She leaves home at 12:20 and arrives at the park at 12:50.
What is her average speed in km/h?

Answer 1

20 km/hr

Explanation:

The total time she takes to travel 10 km is 30 minutes of 0.5 hours.

To calculate speed, we can divide the distance traveled by the time it takes.

`s = (10)/(0.5) = 20` km/hr
