I know this is not a question people usually as but, its collaboration day and if school starts at 9:15 and I leave for the bus at 8:30, at what time would I leave if school started at 10:45?
There are 45 minutes between when you leave for the bus and when school starts. If school were to start at 10:45, you will still leave 45 minutes prior in order to catch the bus. This means that you would leave for the bus at 10:00
