My clock has stopped !! 😦 😦 😦
My only time piece is a wall clock. One day I forgot to wind it and it stopped. I went to visit a friend whose watch is always correct, stayed awhile, and returned home. There I made a simple calculation and set the clock right.
How did I do this when I had no watch on me to tell how long it took me to return from my friend’s home?
