A jogger leaves home at 9:00 a.m., and, without stopping, runs 3 miles to the local running track, runs around the track 8 times, and then runs home along the same route for a total distance of 8 miles. If the jogger arrives home at 10:20 a.m., what is the jogger’s average jogging speed?
Total distance = 8 miles
total Time = 80 minutes = \(\frac{80}{60}\) = 1.33 hrs
Average speed \(= \frac{total distance}{total time} = \frac{8}{1.33} = 6\)
