--------------
Let the speed of the boat in still water be "b":
----------------
Upstream DATA:
distance = 180 miles ; rate = b-5.5 mph ; Time = d/r = 180/(b-5.5)
--------------
At this point you would like to have equation but without knowing
the time for the upstream trip you cannot determine the speed of
the boat in still water.
