Question 845061: Hi. This problem is kind of confusing me.
Tom can paint a fence in 8 hours. Huck can paint the same fence in 5 hours. How long would it take to put two coats of paint on the fence if Tom and Huck work together? (Leave the answer in improper fraction form)
Here's what I came with so far:
1/8 + 1/5= 1/t (t for time)
=5t/40 + 8t/40=13t/40
=13t/12 = 40/13
=t=40/13
But what to do next? How do I find the time it would take them to paint two coats on the fence? DO I multiply by 2?
Help please.

Yes but you have to be sure the first coat is dry.
