Question

David ate 80 blueberries in one hour. How many did he eat in fifteen minutes?

Answer 1

All we have to do is divide how many blueberries he ate in an hour (80) by how many times 15 minutes is in 1 hour (4)

80 ÷ 4 = 20

We can check our work by multiplying 20 by 4

20 x 4 = 80

Therefore, David ate 20 blueberries in 15 minutes

Hope this helps you!

Answer 2

David ate 20 blueberries per hour because there is 60 minutes in an hour. and 60 divided by 4 is 15. So do 80 divided by 4 is 20.
