Emilie is training for her next track meet. She is running on
the track and wishes to run 8 miles. One lap around the
track is 400 meters. There are 1,600 meters in a mile. How
many laps will she need to run to go 8 miles?
If each mile is 1600 meters, she will need to run 4 laps per mile. To run 8 miles, multiple the laps for one mile (4) by the total number of miles (8) to get the total laps necessary (32).
