Question

A boat can travel 10 miles downstream in the same time it
can travel 3 miles upstream. The speed of the river
current is 2 miles per hour. Which equation could you use
to find the speed of the boat in still water?

Answer 1

Answer:

$\frac{10}{x+2} = \frac{3}{x-2}$

Step-by-step explanation:

The 10 represents the speed traveling downsteam while the 3 represents speed upstream. Downstream you have the help of the current, so it would be x + 2, upstream you are working against the current so it would be x - 2.
