Question

A jogger travels 2,000 meters in 12 minutes. What is the joggers average speed in kilometers per hour ? ( don’t forget the units )

Answer 1

10 km per hour

Explanation:

Just set up a proportion:

2,000 meters x meters

---------------------- = -----------------------

12 minutes 60 minutes

Cross multiply:

12x = 120000

x = 10000 meters per hour

In km, it would be hmm... *thinks* 10 km per hour :D
