Question

An athlete can run 9 kilometers in 1 hour. If the athlete runs at that same average speed for 30 minutes, how far will the athlete travel? *

Answer 1

Explanation:

1 hour = 60 minutes

1 kilometers = 1000m

9 kilometers = 9*1000 = 9000 m

Distance traveled in 60 minutes = 9000 m

Distance traveled in 1 minute = 9000/60

Distance traveled in 30 minutes

`=(9000)/(60)*30\\\\=(9000)/(2)\\\\`

= 4500m = 4.5 km
