Answer by Edwin McCravy(20055) (Show Source): You can put this solution on YOUR website! A machine can fill 3864 cartons of milk in 0.4 hour. How many cartons of milk can it fill per hour?
"In" here means "per", so
3864 cartons of milk in 0.4 hour
means
3864 cartons of milk PER 0.4 hour
"PER" means "divided by" or "over":
or 9960 cartons per hour.
