4 laps :-)
About 32.2 laps.
16 laps on a quarter mile track.
if the track is 1/10th of a mile, you would have to make ten laps to equal one mile. you would have make 5 laps to make half a mile. So 10 laps plus 5 laps equals 15 laps.
1609.344 meters equals 1 mile 1609.344/442 equals 3.641 laps Or just under 3 and 2/3rds laps.
i believe it is four laps. But it all depends on what type of tredmill you have.
