Hi, I'm stuck on grade 11 review right now, and it's horrible because the material that I was taught completely changed after I went into grade 12 last year, so now I am stuck on this question, I believe it's too vague. But then again, I didn't keep any of my notes from previous years.

Rowing at 5 times the speed of the current, Jacob's team can travel 24km downstream in the same time it takes them to travel 16km upstream. What is Jacob's team's rate and the rate of the water?

Thank-you in advance.
