Question

Bill ran 10 laps around the high school track in 12 minutes how many laps can be run in 45 minutes

Answer 1

37.5 laps

Explanation:

If we assume that Bill can run at the same speed for 45 minutes, the number of laps will be proportional to the time.

laps/time = 10 laps/(12 minutes) = n laps/(45 minutes)

n laps = (10 laps)(45/12) = 37.5 laps . . . . . multiply by 45 minutes

Bill can run 37.5 laps in 45 minutes.
