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

  • ALGEBRA -

    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 = 8-5.5 = 2.5 mi/h. = Velocity of
    the water.
