Question

An athlete runs 1 mile along a normal 400m athletic track and finishes exactly on the finish line. Where did he start from? ( 1 mile=1.609km)

Answer 1

He started 9 meters before the start/finish line

Explanation:

1mile = 1.609 km

1.609 km * 1000meter/1km = 1609 meters

He ran 1609 meters

each lap is 400 meters

he ran 4 laps

4*400 = 1600

1609-1600 = 9 meters

He started 9 meters before the start/finish line
