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
Do you still need help
so what are u solving for, and i have no idea what those equations mean..
I think you can turn it into relative velocity problem
r= rate c=current
solve for currren...question is at the top
River speed+Boat Speed= Actual Speed
River speed we denote x for downstream -x for upstream
i need it done by the eqution i have set up
