Asked by Jaunice

I am rowing on a river between two cities that are 19 miles apart. When going downstream, I make the journey in .76
hour(s). When I return upstream, it takes me 2.11
hour(s).

What is the current of the river? what is the speed I would row in still water?

If my speed is s, and the current is c, then since

distance = speed*time,

.76(s+c) = 19
2.11(s-c) = 19

Now just solve for s and c.
