The Smith household is experiencing a hectic morning. John, the father, has an important meeting scheduled for 10:00 AM, while his wife, Emily, must drop their children, Ben and Sarah, off at school by 8:30 AM. The school is located 20 minutes away from their home. John's meeting is 30 minutes away, but he needs to stop at the bank first, which is conveniently on the way to the meeting location. However, the bank does not open until 9:00 AM. Emily has a hair appointment at 11:00 AM, which is 15 minutes from the meeting site. Ben has soccer practice at 3:00 PM, and Sarah has a piano lesson at 4:00 PM. The family owns two cars, but one is currently in the shop for repairs. Their maid, Mrs. Johnson, is available to drive one of the children to their after-school activities. Given these time constraints, what is the earliest time John can leave for his meeting?
