- Meeting Trains
- At Wurzeltown Junction an old lady put her her head out of the window and shouted:
- "Guard! how long will the journey be from here to Mudville?"
- "All the trains take five hours ma'am, either way," replied the official.
- "And how many trains shall I meet on the way?"
- This absurd question tickled the guard, but he was ready with his reply:
- "A train leaves Wurzletown for Mudville, and also one from Mudville to Wurzletown, at five minutes past every hour. Right away!"
- The old lady induced one of her fellow passengers to work out the answer for her.
- What is the correct number of trains?
