50 miles = 60 minutes 5 miles = 6 minutes 15 miles = 18 minutes
15 minutes.
9 mph for 1 hour and 40 minutes is 15 miles. 1 hour at 9 mph = 9 miles 40 minutes at 9mph = 6 miles 9 miles + 6 miles = 15 miles
11/2 miles in 15 minutes = 6 mph
15 minutes = 1/4 hour so 125 mph for 1/4 hour = 125/4 miles = 31.25 miles.
If you could drive 184 miles in 15 minutes, multiply 184 by 4 (15 minutes is one-quarter of an hour) to get your MPH. In those 15 minutes, your average speed was 736 MPH.
