Question

It takes 16 hours for 3 people to mow a lawn. How many people would be needed to mow it in 6 hours?

Answer 1

8 people

Explanation:

3 people to do the job in 16 hours so each of the people will mow 1/3 of the lawn during the 16 hours.

So if was a single person was mowing the lawn would take them 3 times longer 16*3 =48 hours

To mow the lawn in 6 hours will need 48 hours to be split in 6 hours so will get 48/6 = 8 people.
