Distance cannot be expressed in time. If it could, then you'd be able to figure out how many minutes high your house is, and how many miles of sleep you had last night.

75 miles at a constant speed
8mph
1 hour = 60 min so each one mile = 1 min when 60 mph there for 17 miles will be 60/50*17= 20.40 min.
11.25 miles per hour ============= Solution Method: ----------------- There are 60 minutes in 1 hour. We often say there are 60 minutes per hour. We express this relationship mathematically as: 60 min/hr To convert miles/min to miles/hr, do the following: 1.5 miles/8 min * 60 min/1 hr = 1.5 * 60 / 8 = 11.25 miles/hr (average speed) * Note: minutes cancel in the numerator & denominator). ---------------- Original answer: Just over 12 miles per hour.
Use dimensional analysis/unit analysis/factor label (all different terms for the same concept). 7 miles/second * 60 sec/min * 60 min/hour = 25200 miles/hour
