Question

A speedboat can travel 32 miles per hour in still water. It travels 150 miles upstream against the current then returns to the starting location. The total time of the trip is 10 hours. What is the speed of the current?

Answer 1

We know

D = RT

D is distance

R is rate

T is time

Upstream rate = x - c

Downstream rate = x + c

note: c is rate of current and x is still water rate (x)
