Answer 1

John needs to get up at 7:10 am.

Step-by-step explanation:

To determine the time John needs to get up in order to make it to school and not be tardy, we need to add up the time it takes for him to walk to school, eat breakfast, and get ready.

It takes him 20 minutes to walk to school.

It takes him 10 minutes to eat breakfast.

It takes him 20 minutes to get ready.

Adding up these times gives us a total of 50 minutes. Therefore, John needs to get up 50 minutes before 8:00 am, which is 7:10 am.
