Last weekend I travelled to my sister's house in Glasgow, around 250 miles away. I started on Saturday morning at 7am, traffic was heavy in places, and at times I was stationary. I arrived sometime after lunch.
On Sunday, it was time to make my way home, over exactly the same route. I left my sister's at exactly the same time, 7am, however, this time I came straight home without any travel delays, arriving home just before lunch.
How likely is it that I was at exactly the same point at exactly the same time on both days?
