Jim paddles a canoe upstream at a rate o 3mi/hr. Traveling downstream, he travels at 8 mi/hr. What is his rate in still water and what is the rate of the current?
PLEASE SHOW THE SOLUTION EQUATION

Eq1: Vc  Vw = 3
Eq2: Vc + Vw = 8
Add the Eqs:
2Vc = 11
Vc = 5.5 mi/h = Velocity of canoe in
stil water.
In Eq2, substitute 5.5 for Vc:
5.5 + Vw = 8
Vw = 85.5 = 2.5 mi/h. = Velocity of
the water.
