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

14.6 miles, 38 min
10:05 --> 10 * 60 min + 5 min = 605 min 08:20 --> 8 * 60 min + 20 min = 500 min 605 min - 500 min = 105 min (= 1 3/4 hr)
10.37 min/mile = 1/10.37 miles/min 1/10.37 miles/min X 60 minutes/hour = 60/10.37 miles per hour = 5.786 miles per hour
6.2 miles in 55.31 min = 6.2 mi / 55.31 minDivide by 55.31 = 0.1121 miles per min
80 miles in 16 min = 5 miles per min.
75 miles at a constant speed
(3 miles=30 min)x2=((6 miles=60 min)/60 min)=(6 miles= 1 hr)=(6 miles/hr)
1 hr = 60 min ⇒ 1 hr 13 min = 1 x 60 + 13 min = 73 min 13 miles in 73 min → 1 mile in 73 ÷ 13 min = 58/13 min/mile ≈ 5.62 min/mile
