GeekDad Puzzle of the Week – Student Dropoff

school_exterior_1000x500The small school that Nora attends has three standard parking spots out front for parking when you drop your child off or pick them. On the Tuesdays and Thursdays mornings last year I got to drop her off last year, I would meet and talk with to the other parents dropping off their children.

If there are 15 different vehicles (including mine) that drop children off, it would take at least 3 1/2 weeks (7 mornings) for me to be parked with the other 14 vehicles, two other vehicles at a time — assuming I met no vehicle twice during that time.

Is it possible that for these 7 mornings that no one would would meet the same vehicle twice dropping their child off? If it is possible, what would this look like (in a diagram, chart, list, etc.)? If it isn’t possible, why not?

As always, please submit your response to GeekDad Central and correct (or reasonably correct) responses will be put into a drawing for this week’s fabulous prize: a $50 Gift Certificate from ThinkGeek.

Good luck, and happy puzzling!
