A kayaker paddled 2 hours with a 6 mph current in a river. The return trip against the same current took 3 hours. How do you find the speed the kayaker would make in still water?
D = RT
As the Distance is the same
Let K equal the rate of the Kayaker in still water
Multiplying across the parenthesis gives
Adding the opposite to both sides of the equation gives
The result is
Dividing both sides by 5
