Emily catches the school bus at 7:45 am she needs 30 minutes to get dressed 15 minutes to eat breakfasts, an 10 minutes to walk to the school bus. What latest time Emily can awake in the morning to get to the bus on time?

6:50 am

Step-by-step explanation:

emily need 45 minutes to get dressed and eat breakfast which makes the time 7:00am then needs an extra 10 minutes to walk to school, therefore she needs to wake at 6:50am

6:50. If she wakes up at 6:50, and uses 30 minutes to get dressed, the time would be 7:20. Then if she uses 15 minutes to eat, the time would be 7:35. Lastly, if she uses her 10 minutes to walk, she'd catch the bus at 7:45. I don't know why anyone would test their luck with that time, but that's the answer. 6:50
