Jennifer Chan has just enough money to rent a canoe for 2 1/2 hours. How far out on the lake can she paddle and return if she paddles 3 km/h and back at 2 km/h?
-------
Out DATA:
rate = 3 km/h ; distance = x km ; time = d/r = x/3 hrs
------
In DATA:
rate = 2 km/h ; distance = x km ; time = d/r = x/2 hrs
------
Equation:
x/3 + x/2 = 5/2 hrs
------
2x + 3x = 15
------
x = 3 km (distance out)
------
