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?

• ALGEBRA -

Eq1: Vc - Vw = 3
Eq2: Vc + Vw = 8
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 = 8-5.5 = 2.5 mi/h. = Velocity of
the water.
