One lap around a track is equal to one-fourth of a mile. A horse ran a distance of 9 laps in 2 minutes and 30 seconds. What was the horse’s average speed in miles per minute?
one lap is .25 miles. so 9 laps would be 2.25 miles in 2.5 minutes. miles/minute is what we are trying to find. it is exactly what it looks like the amount of miles divided bye he amount of minutes, so 2.25/2.5 ur answer is 0.9 miles/minute
