Question

Denny can deliver 6 papers every 15 minutes and Brendan can deliver 5 papers in that same amount of time.How many papers can they deliver in an hour?

Answer 1

44 newspapers

Denny delivers 6 papers in 15 minutes. Brendan delivers 5 papers in 15 minutes. So they can deliver 6 + 5 = 11 papers in 15 minutes.

Since we need to know how many they can deliver in an hour, we just multiply our answer by 4 because that's how many 15 minutes are in an hour.
