Question

One lap around a track is one-eighth of a mile. A horse ran a distance of 11 laps in 3 minutes and 30 seconds. What was the horse's average speed in miles per minute?

Answer 1

9 laps = 9(1/8) or 9/8 miles

speed = (9/8) / 2.5 minutes
= 1.125/2.5 mpm
= .45 miles/min

Answer 2

Young Trippy -- please correct your typo.

Answer 3

(11(1/8)mi)/(3 1/2 min) = (11/8)/(7/2) = 11/8 * 2/7 = 11/28 mi/min

Answer 4

yep
