During the first part of a trip, a canoeist travels 33 miles at a certain speed. The canoeist travels 2 miles on the second part of the trip at a speed 5 mph slower. The total time for the trip is 4 hours. What was the speed on each part of the trip?
The speed on the first part of the trip was _____mph

Let the speed on the first part of the trip be x.
33/x+2/(x5)=4
Solve for x and reject any solution less than x=5 mph.
