A boat going upstream on The River averages 3 mph. Going downstream, the boat averages 7 mph. Find the speed of the current and the speed of boat in still water.
----------
The boat's "waterspeed" is the average of up and downstream.
The current is the difference between boatspeed and either up or downstream.
