Bennett spent 4 hours at school today. He attended three 70-minute classes. There is a 5-minute break between classes. Then he ate lunch before going home. How long did Bennett spend eating lunch?

20 minutes

Step-by-step explanation:

70 minute classes times 3

Plus 2 breaks one in between 1st and 2nd class

And another in between 2nd and 3rd class

Which = 220 minutes

4 hours times 60 (because 60 minutes per hour)

Gives us 240 minutes

Then you subtract total time from time in classes and breaks

Which gives us 20 minutes for lunch time
