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|

    20r+20c=8 and 30r-30c=6

    I think you can turn it into relative velocity problem

    River speed we denote x for downstream -x for upstream
