in still water, a paddle boat averages 10 miles per hour. It takes the boat the same amount of time to travel 36 mile downstream, with the current as 24 miles upstream, against the current. What is the rate of the water's current?

• Intermediate Algebra -

time = distance/speed

36/(10+c) = 24/(10-c)
c = 2
