**drwls**, Sunday, May 27, 2012 at 1:11amLet the distance paddled (one way) be L = 480 m

Let V be the canoe speed in still water and v be the stream speed.

L/(V+v) = 60 s

L/(V-v) = 80 s

(V+v)/(V-v) = 80/60 = 4/3

V + v = (4/3)V - (4/3)v

V/3 = (7/3)v

v = V/7

480/(8V/7) = 60

V = 7 m/s

v = 1 m/s
