This question cannot be answered sensibly. A mile per hour is a measure of speed, with dimensions [LT-1]. A minute is a measure of time, with dimensions [T]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
20 minutes equals 20/60 hours or 1/3 hour. 1/3 of 30 miles in an hour is 10 miles.
96 minutes
15 minutes = 1/4 of an hour
(1 mile/3 min) * (60 min/1 hour) = 20 MPH.
(19.76 miles)/[(42.23 minutes)/(60 minutes/hour) = 28.08 miles/hour, to the justified number of significant digits.
40 minutes
270 feet in 10.8 minutes equals 0.284 miles per hour.
10 miles15 minutes is a quarter of an hour. Therefore: 40 mph divided by 4 parts per hour equals 10 miles.
20 minutes equals 20/60 hours or 1/3 hour. 1/3 of 30 miles in an hour is 10 miles.
1/12 th of an hour equals how many minutes?
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
96 minutes
15 minutes = 1/4 of an hour
(1 mile/3 min) * (60 min/1 hour) = 20 MPH.
(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
60 minutes
