Question

Alex goes on a river boat tour while on vacation. The maximum speed of the boat in still water is 13 miles per

Answer 1

Answer:

The equation to solve is

$\frac{24}{13+s}=\frac{15}{13-s}$

The rate of the current s is 3 mph

Step-by-step explanation:

Remember that

The speed is equal to divide the distance by the time

so

The time is equal to divide the distance by the speed

Let

s ---> the rate  or speed of the current in mph

we know that

The linear equation that represent this situation is

$\frac{24}{13+s}=\frac{15}{13-s}$

solve for s

$24(13-s)=15(13+s)$

$312-24s=195+15s\\24s+15s=312-195\\39s=117\\s=3\ mph$
