Question

Solve by using a system of two equations in twovariables. Gretchen paddles a canoe upstream at 3 mi/h.  Traveling downstream, she travels at 8 mi/h What isGretchen's paddling rate in still water and what is the rate of thecurrent?

Explanation / Answer

Let x by Gretchen's speed in still water, y be the speed ofwater. Traverling upsteam, the speed of water cancels out Gretchen'sspeed of the canoe so his traveling speed is slower than normal instill water --> x - y = 3 In the other way, traverling downstream, the water actuallyhelps the canoe and speeds it up. --> x + y = 8 Solev those two equations you can get x = 5.5, y = 2.5 so the conoe's speed in still water is 5.5 m/h
