The answer uses equations to determine the time each boy needs to paint a fence, showing the step-by-step process with clear explanation.
To solve this problem, we can set up equations based on the given information.
Let's denote the time Larry takes to paint the fence as x hours. Therefore, Tom takes (x - 3) hours to paint the fence.
When working together, their combined work rate is 1/((x - 3) + x) = 1/2. Solving these equations will give you the time each boy alone needs to paint the fence.
