Modern Puzzles by Henry Ernest Dudeney: $44$
- Find the Distance
- A man named Jones set out to walk from $A$ to $B$,
- and on the road he met his friend Kenward, $10$ miles from $A$, who had left $B$ at exactly the same time.
- Jones executed his commission at $B$ and, without delay, set out on his return journey,
- while Kenward as promptly returned from $A$ to $B$.
- They met $12$ miles from $B$.
- Of course, each walked at a uniform rate throughout.
- Now, how far is $A$ from $B$?
- I will show the reader a simple rule by which the distance may be found by anyone in a few seconds without the use of a pencil.
- In fact, it is quite absurdly easy -- when you know how to do it.
