How should I solve this?

Question

Jim and Kim can paint a fence in 144 minutes. (This assumes that both work the whole time and that each works at a constant pace.) Jim working alone could paint the whole fence in two hours less than it would take Kim working alone to paint the whole fence. How long would it take Kim working alone to paint the whole fence?

Answer 1

Set it up as an algebra problem, with one standard variable, and the other variable is dependent on the first.

I will not solve it for you, that is a violation of the Wyzant honor code. You figure it out.
