Question

Six people can finish painting a wall in 5 hours. If only 2 people are available, how many hours do they have to work to finish the same job?

Answer 1

Answer:

If it takes 5 people 5 hours, then that is 25 hours of painting.

If there are only 2 people, then they would have to paint for 12.5 hours each.

Unless one of those people is my wife. Then I would have to paint for 23 hours, and she would paint for 2, leaving her plenty of coffee break time.
