What if a fence painting competition allowed pairs to compete? If Ben Rogers can paint the fence in 8 min on his own and Johnny Miller can paint it in 6 min, then how long would it take them working together? If Ben can paint a single coat of the fence in 8 min, then how much of the fence could Ben paint in 1 min?

If Johnny can paint a single coat of the fence in 6 min, then how much of the fence could Johnny paint in 1 min?

If Ben and Johnny work together to paint a single coat of the fence, then let t represent the amount of time they each spend painting. What operation should be used to set up an equation that represents how long they would take to paint a single coat of the fence?

Solve the equation for t. How long will it take Ben and Johnny to paint the fence? Round your answer to the nearest tenth of a minute.
