One absentminded ancient philosopher forgot to wind up his only clock in the house. He had no radio, TV, telephone, internet, or any other means for telling time. So he traveled on foot to his friend's place few miles down the straight desert road. He stayed at his friend's house for the night and when he came back home, he knew how to set his clock. How did he know?

If his friend had any means of telling the time and supposing the journey to and fro was approximately the same amount of time, the philosopher can now set his clock. Rajorshi Chaudhuri · 2 years ago
