Benita runs 500 meters a day for 10 days. How many kilometers does she run?

Answer 1

Hi Claire! The best way to do unit conversions, is to make sure you keep your units...

1 km = 1000 m so...

500 m/day x 1 km/1000 m = ?? km/day (the meters cancel out) but she ran that for 10 days, so you will need to multiply by 10:)

Answer 2

10*500=5000 m = 5 km
