Let 
represent the time of each of the downstream and upstream trips. Let 
represent the speed of the current. Distance equals rate times time, hence time equals distance divided by rate. The current goes against the speed of the boat upstream and adds to the speed of the boat downstream.
and
since 
, we can say:
Simply solve for
