Suppose a boat is traveling 44 mph up a very long river. The river is flowing at a rate of 4 mph downstream. Assuming the boat continues at a constant speed and the river continues to flow at a constant rate, how long will it take to travel 200 miles upstream?
----------------
The boat's groundspeed, or speed with respect to the Earth is 44 - 4 = 40 mi/hr.
----------
d = r*t
t = d/r
