A group of college students are volunteering for Help the Homeless during their spring break. They are putting the finishing tou
ches on a house they built. Working alone, Irina can paint a certain room in 7 hours. Paulo can paint the same room in 6 hours. Write an equation that can be used to find how long it will take them working together to paint the room. How many hours will it take them to paint the room? If necessary, round your answer to the nearest hundredth.
The question is asking to compute on how many hours will it take them to paint the room and base on the question and the given data in the problem, I would say that the answer would be 1/7+1/6 = 1/x, 6.5 hours. I hope you are satisfied with my answer and feel free to ask for more
