---------------- Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website! To find mi/hr, divide the miles by the hours.
-------
5 miles in 2 hours = 5mi/2hr = 5/2 mi/hr
---
12 miles in 4 hours = 12mi/4hr = 3 mi/hr
Including the units makes it make sense.
Cost of fuel in $/gallon - divide the dollars by the gallons.

Seems obvious.
