Two friends are cleaning a pool. Roger can clean it in 6 hours working alone. If Latonya works alone, it will take her 5 hours. How long will it take them working together? Round to the nearest tenth.
I'm not sure about the setup of this problem at all.
I think it's something like
x/6 + x/5 = x? I know that's not right but I'm not sure what to do about it.
