Question

If a canoe travels 6 miles per hour downstream, and 2 miles per hour p stream, how many miles per hour will it go in still water?

Answer 1

4 Miles an hour

Explanation:

Answer 2

4 miles per hour

Explanation:

The given relations allow us to write two equations.

__

The downstream speed is the sum of the canoe speed and the stream speed:

6 = c + s

The upstream speed is the difference of the canoe speed and the stream speed:

2 = c - s

Adding these two equations, we get ...

8 = 2c

4 = c . . . . . divide by 2

The canoe speed in still water is 4 miles per hour.
