I'm trying to add time. The quoestion is I have to be at school at 8:30. If I do the following what time do I leave the house. shower 35 minutes, get dressed 23 minutes, exercise 18 minutes, my time 40 minutes. I know the answer just don't know how to get it.
Your question is confusing.
I assume the things you have to do -- shower, dress, and exercise are things you do at home, before you leave for school. Did you intentionally leave out eat breakfast?
35 + 23 + 18 = 76 minutes = 1 hour, 16 minutes
You didn't say how long it takes you to get to school. Are you trying to figure out what time you need to get up?
Please clarify your question and someone will try to help you.
