A boat traveled 240 miles downstream and back. The trip downstream took 10 hours. The trip back took 40 hours. Find the speed of the boat in still water and the speed of the current.
----------------------
Find the 2 speeds, up & down stream, using d = r*t
----
Find the speed of the boat in still water
= the average of the 2 speeds.
--------------------
and the speed of the current.
= the difference between the boat's speed and either of the other 2.
