50 miles in 10 minutes is the same as 300 miles per hour, since 50 miles/10 minutes * 60 minutes/1 hour = 300 miles per hour
(19.76 miles)/[(42.23 minutes)/(60 minutes/hour) = 28.08 miles/hour, to the justified number of significant digits.
Here is the explanation: 2 miles/16 minutes X 60 minutes/hour = 7.5 miles per hour
It depends on the speed. At 10 miles per hour 100 miles is 10 hours. At 100 miles an hour it is 1 hour. At 1000 miles an hour it is 0.1 hour (= 6 minutes).
28 miles in 1 hour 38 minutes equates to an average speed of 17.14 miles per hour.
2.58 miles / 61 minutes * 60 minutes/hour ~= 2.538 mph
51.5 minutes.
At 1 mile per hour it is 55 hours, at 2 miles an hour it is 27.5 hours at 5 miles an hour it is 11 hours at 55 miles an hour it is 1 hour at 60 miles an hour it is 55/60 hour or 55 minutes at 120 miles an hour it is 27.5 minutes at 550 miles an hour it is 6 minutes etc
That is about 4.3 miles per hour.
