Take this riddle for example from The Bioneer.

https://www.thebioneer.com/image-streaming/

A monk takes a journey up a mountain that takes him one whole day. He varies his pace, stopping along the way for food and slowing down at points to enjoy the scenery. When he reaches the top, he stays in an old monastery for 24 hours to meditate and then begins the journey back. He sets off at the same time and takes a whole day again. Once more, he varies his pace but he takes the exact same route he did on the way up.

Question: is there any time of day when the monk would have been at the exact same point on his route on both days? At any point was the monk in the same place, at the same time, on both days?
