Question

IF JOHN RAN A 5-KILOMETER MARATHON HOW LONG WAS THAT IN METERS?

Answer 1

A kilometer is composed of 1000 meters. The term "kilo" means "a thousand."

So 5 kilometers means 5 1000 meters, thus it is equal to 5,000 meters.

1 km = 1000 meters

5 km * 1000 m / km = 5 * 1000 m = 5,000 meters

1 m = 0.001 km

5 km * 1m/0.001km = 5 m / 0.001 = 5,000 meters
