Answer:

4.17 hours before lunch

Explanation:

Ellen has 4 classes before lunch break, which means she has 3 passing periods between those classes. Each passing period is 10 minutes long, so the total time for passing periods is 3 x 10 = 30 minutes.

The duration of each class is 55 minutes, so the total time for 4 classes is 4 x 55 = 220 minutes.

To find the total time Ellen spends in class and passing periods, we need to add the time for the classes and the time for the passing periods:

Total time = time for classes + time for passing periods

= 220 minutes + 30 minutes

= 250 minutes

To convert the time to hours, we can divide by 60:

Total time in hours = 250 minutes ÷ 60

≈ 4.17 hours

Therefore, Ellen's classes start approximately 4.17 hours before lunch break.

I hope this will help you!
