Justin runs on a track that is 1/4 mile long. Today, Justin ran around the track in 13 1/2 minutes. Did Justin run faster or slower than 6 miles per hour duirng todays run?

Definitely slower! why?

because it is 4 laps around the track just to make 1 mile. he would have had to run 24 laps in an hour. it took him 13.5 to run just one. he would have run just a little over a mile in an hour. or a little over 1 mph
