Question 517058: it takes 9 people 1 hour to mow 6 acres of land, how many people would it take to mow 24 acres in 3 hours?
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! If it took 1 hour for 9 people to mow 6 acres of land,
It would take 4 times as many people to mow 4 times
as much land in the same amount of time, so
36 people can mow 24 acres in 1 hour
If you give them 3 times as long to mow it, you only
need 1/3 as many people, so
12 people can mow 24 acres in 3 hours
