Question 708796
Let x=amount of time it takes 2 workers to paint the house
If 4 workers can paint the house in 8 hours, then 1 worker can paint the house in 4*8=32 hours
In other words, the house requires 32 man-hours to paint
Soooo  our equation to solve is:
2*x=32
x=16 hours

Hope this helps---ptaylor
