It takes Sandy three hours to paint a fence, and it takes Claude six hours to complete the same job. How long would it take both of them working together to complete the same job? Explain.
9, because they both paint the fence. LOL!
2.25 Hours?
((3 / 2) * 1.5)
Nope @ you both
Trust -- it's not a trick question
Simple mathmatics. :)

If one of them can do it in 3 hours, how could it
possibly take longer than 3 hours?
Claude is going to slow Sandy down.
2 hours?
Sandy would have done 2/3.
Claude would have done 1/3. ?

Good thing this forum doesn't knock off points for spelling!
The sad thing is, I wrote mathematics before I did mathmatics. :P
