Let Johns speed with respect to the water be km/h, then whenOriginally Posted bysugar_babee

rowing with the flow he is travelling at km/h, and against the flow

km/h.

He rows km with the flow and km against the flow.

These take h, and h respectively

and their total is h.

So we have:

.

Now we have translated the word problem into a mathematical problem, it

remains to solve , and check which of the answers make

sense for this problem
