twenty miles per hour 3 minutes = 1 mile 6 minutes = 2 miles 60 minutes = 20 miles
80 miles in 20 minutes equates to an average speed of 240 miles per hour.
(.25 miles / 3 minutes) * (60 minutes / 1 hr) = (.25 * 60)/3 = 5 mph If you run a quarter mile in 3 minutes, your average speed is 5 mph.
Your speed is 39 miles per hour.
