Question

Please How Steps Donnie ran a boat against the current that flowed 20 mph for 3 hours. He ran with the current for 1.5 hour. How fast would he be riding on still water?

Answer 1

well the current speed is 20 mph and his "own" speed is v.
Let the distance be d.

Then we know that:
(v - 20) * 3 hours = d
When he runs with the current.
(v + 20 ) * 1.5 = d

From here you should be able to solve for v. Do you think you can do that? :)

Answer 2

Yes thank you very much! :)

Answer 3

No problem :)
