You can put this solution on YOUR website! Bill can travel 36 miles upstream in his hovercraft in 3 hours. If he can return in 2 hours, how fast can Mr. Compton travel in still water?
----------------
A hovercraft is affected only slightly, if at all, by the current. It's definitely not a linear function.
---------------
If this were a boat:
Find the 2 speeds, upstream and downstream.
To find miles per hour, divide the miles by the hours.
----
His water speed is the average of the 2 speeds.
