Five people can mow a lawn in 12 hours. How many more people are needed to mow the lawn in just 3 hours, assuming each person mows at the same rate?

1 lawn / (5 people 12 hours)  =   1 l / 60 p-h

 

1 / 60 p-h  x 3 hr = 3/(60  p)           60/3 = 20 people    needed      or      15 MORE people needed
