60/4=15, so the swimmer did 8 laps in 15 minutes, so 8*4 = 32
The swimmer does 32 laps per hour.
The swimmer does 32 laps per hour.
if you are asking for rate of laps per hour then you would simply multiply both numbers by 4 so 1/4 times 4 is 1 full hour and 8 laps times 4 would equal 32 so the rate of laps per hour would be 32 laps per hour. hope this helps
