Explain this. hello, i'm terrible at word problems, and i was hoping someone could give me the written equation and explain why for this word problem. (not fully worked out to answer) here is the problem "anita can clean a typical pool in 8 hours. chao can clean a typical pool in 6 hours. how long should it take anita and chao working together to clean a typical pool? show all your work. leave your final answer as an integer or reduced fraction." in advance!
