during the first part of a trip, a conoeist travels 70 miles
at a certain speed. the canoeist travles 7 miles on the second
part of the trip at a speed of 5 mph slower. the total time
for the trip is 5 hrs. Ehat is the speed on each part of the trip?

Assume the speed for the first trip is v and the speed for the second trip is
(v  5)
Since time = distance/speed, you get:
(70)/(v) + (7)/(v  5) = 5 hrs.
Solve for v to get the first speed, then subtract 5 to get the second speed.
