Edie can paint a wall in 3 hours. Dan can paint the same wall in 6 hours. If they work together, how many hours will it take Edie and Dan to paint the wall?
To solve the problem, we need to use the formula:
time = amount of work / rate of work
Let's let x be the amount of time it takes for both Edie and Dan to paint the wall together.
The amount of work is the entire wall, which is 1.
The rate of work for Edie is 1/3 (as she can paint the wall in 3 hours).
The rate of work for Dan is 1/6 (as he can paint the wall in 6 hours).
So, using the formula:
x = 1 / (1/3 + 1/6)
x = 1 / (2/6 + 1/6)
x = 1 / (3/6)
x = 2
Therefore, it would take Edie and Dan 2 hours to paint the wall if they work together.
