during the first trip a canoeist travels 79 miles at a certain speed. the canoist travels 24 miles on the second part of the trip at a speed of 5 mph slower. the total time for the trip is 5 hrs. what was the speed on each part of the trip

time=time1+time2
5= 79/v + 24/(v5)
multiply both sides by v*(v5)
gather terms,solve.
