A motorboat can go 8 miles downstream on a river in 20 minutes. To travel the same 8 miles upstream, the boat takes 30 minutes. Find the speed of the current.

I think you have to find speed in both cases and the difference will be the speed of the current: V1 = 8/20 V2 = 8/30 V = |V1-V2|
i have an equation set up but can u review it?
sure post it
20r+20c=8 and 30r-30c=6
=8 not 6
