Question 496091: The speed of a stream is 4mph. If a boat travels 44miles downstream in the same time that it takes to travel 22 miles upstream, what is the speed of the boat in still water? Answer by chessace(471) (Show Source):
You can put this solution on YOUR website! Time = dist / speed = 44 / (S+4) = 22 / (S-4)
22(S+4) = 44(S-4)
/22 and distribute: S+4 = 2S-8
S=12 mph
