Question

The time it takes to clean the house varies inversely with the number of people cleaning. If it takes 1 person 4 hours to clean the house, how long will it take 3 people?

12 hours

Your answer doesn't make sense.

I somehow typed 12 because I saw a 4 and 3
So how would you set up the equation
Ms. Sue
Don't worry about an equation. Use your head and figure it out. I'm sure you can come close by estimating.
