You can put this solution on YOUR website!
r, boat speed in still water
c, speed of the river current

                  SPEEDS      TIME        DISTANCE(kilometers)

UPSTREAM           r-c          4          152

DOWNSTRM           r+c          4          232

RATE=DISTANCE%2FTIME

system%28r-c=38%2Cr%2Bc=58%29

You can finish.
