Question

If it took 6 people 9 hours to build a barn, how long would it take 12 people to build the same barn?

Answer 1

Hello!

You have to find what they did to the people

12 / 6 = 2

They doubled the amount of people which means the time will be cut in half

9 / 2 = 4.5 hours

The answer is 4.5 hours or 4 hours and 30 minutes

Hope this helps!
