<PRE><B>Question 750829</B>
If Rita is paddling her canoe upstream against the current at a speed of 2mph and later travels downstream from the current at a speed of 3mph, what is the average speed in still water
------
Upstream Eq::: b - c = 2 mph
Downstream Ea: b + c = 3 mph
-----------------------------------
2b = 5
b = 2.5 mph (speed of the boat in still water)
-------------------------------
Cheers,
Stan H.
