Question 823831: lauren paddles her kayak 8 miles upstream in 4 hours, she turns around and paddles downstream to her starting point in 2 hours. what is the rate at which lauren paddles in still water? what is the rate of the rivers current? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! ---
s = d / t
---
x = kayak speed
y = water speed
---
upstream:
x - y = 8/4 = 2
---
downstream:
x + y = 8/2 = 4
---
x - y = 2
x + y = 4
