A Tibetan monk leaves the monastery at 7:00 A.M. and takes his usual path to the top of the mountain, arriving at 7:00 P.M. The following morning, he starts at 7:00 A.M. at the top and takes the same path back, arriving at the monastery at 7:00 P.M. Is there a point on the path that the monk will cross at exactly the same time of day on both days?

Answer "y" for yes or "n" for no.
