    Call the rate in still water vs;

    upstream you have: vs-v=6/4

    downstram you have: vs+v=6/3

    where v is the rate with which the river flows.

    rearranging:

    vs-v=3/2

    vs+v=2

    from the second you have v=2-vs substitute into the first:

    vs-2+vs=3/2

    2vs=7/2

    vs=7 mi/hr
