A group of ten students needed to travel home for the Holidays. Not more than three of them live in the same town. At least two of them would like to visit their fellow classmates. One of them has a family member abroad. It would take the student who lives the furthest 14 hours to get home by car while it would only take the nearest student only an hour by train.
What would be the most efficient way for all the students to travel home for the Holidays?
