Alan and Betty are exercising on a track. They both left the starting point at the same time, and returned at the same time. Alan walked once around the track, while Betty was running several times in the same direction and overtook Alan once during the exercise, and they met up at the end.
If Betty was running in the opposite direction, how many times would she have met Alan?
