Jackie's mail route has 350 mailboxes. She can deliver mail to 50 mailboxes per hour. If she has delivered mail to 150 mailboxes so far, how many more hours will Jackie need to finish her route?
Okay, Jackie starts with 350 mailboxes, but has delivered to 150, so she only has to deliver to 200 more. She can deliver to 50 mailboxes per hour. So 200/50 = 4. The answer is 4 hours.
