Question 1102342: "A boat's crew rowed 39 kilometers downstream, with the current, in 3 hours. The return trip upstream, against the current, covered the same distance, and it took 13 hours. Find the crew's rowing rate in still water."
The question does not say how fast (mph) the current is like the examples we covered in the class powerpoints.
Am I missing something in order to set this up properly?

Question 1102790: A sea turtle is out for a swim. with the current, it can travel 35 miles in 5 hours . In the same time, it can travel 15 miles against the current. Find the speed of the sea turtle and the speed of the current.
So I tried doing this to solve it,
(x+y) speed with current
(x-y) speed against current
Using distance = time x speed
5(x+y)=35
5(x-y)=15
