Question

Tanya and Tim can clean the house in 3 hours. Their 3 children can do the same in 6 hours. How long would it take to clean the house if the whole family will do it together?

Answer 1

Answer: 2 hours

Step-by-step explanation: I believe it’s 2 hours because, if it takes Tanya and Tim, 3 hours to clean the house and their 3 children to clean the whole house, 6 hours then we divide 6 and 3. That makes us get 2 hours, which seems pretty good to me.
