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?

  • algebra -

    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.
