Question 467897: Two boys can clean the yard in 6 hours. How many hours would it take 3 boy to clean the same yard if each boy works at the same rate? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! If 2 boys clean a yard in 6 hrs, then
1 boy would take twice as long, so
1 boy cleans the yard in 12 hrs.
3 boys would take 1/3 of that time
to clean the yard.
3 boys will take 4 hrs to clean the yard
