This question cannot be answered sensibly. A mile per hour is a measure of speed, with dimensions [LT-1]. An hour is a measure of time, with dimensions [T]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
45 miles in three hours at 15 miles per hour.
65 miles per hour x 4 hours = 260 miles
84 miles18 miles/hour * 3 hours = 54 miles15 miles/hour * 2 hours = 30 miles54 miles + 30 miles = 84 miles
at 60 miles per hour it is 21.25 hours
To get the rate for 250 miles in 5 hours, divide the miles by the hours to get miles per hour, 250 miles/5 hours=50 miles per hour. If you divide 5 hours by 250 miles, you get 0.02 hours per mile, the other unit rate for this set of numbers.
At 60 miles per hour, six hours. At 30 miles per hour, twelve hours.
1 hour at 14 miles per hour. 2 hours at 7 miles per hour.
45 miles in three hours at 15 miles per hour.
6.25 hours at 65 miles per hour = 406.25 miles
90 miles per hour.
334 kilometers per hour is 207.54 miles per hour.
It depends how fast you drive. 126 miles per hour? one hour. 63 miles per hour? two hours. 31.5 miles per hour? four hours.
Formula: km per hour x 0.62147 = miles per hour (mph)40 km/h x 0.62147 = 24.8588 mph
32 miles per hour.
A submarine that travels 56 miles in 4 hours averages 16 miles per hour. (The 56 miles divided by 4 hours = 16 miles per hour.) To cover 700 miles at 16 miles per hour will take 700 miles divided by 16 miles per hour = 50 hours.
miles per hour * 7 60mph * 7 hours = 420 miles
You drove 91.25 miles.
