A girl needs to be at school by 7:45 AM. If it takes her 20 minutes to get dressed, 15 minutes to eat breakfast, and 12 minutes to walk to school, what time should she get up at the latest?

Answer 1

To calculate the latest time the girl needs to get up, we can add the time it takes for her to get dressed, eat breakfast, and walk to school.

20 minutes (getting dressed) + 15 minutes (eating breakfast) + 12 minutes (walking to school) = 47 minutes

Therefore, the latest time she should get up is 47 minutes before 7:45 AM, which is 6:58 AM.
