Henry Ernest Dudeney/Puzzles and Curious Problems/80 - A Little Train Puzzle

by : $80$

 * A Little Train Puzzle
 * A non-stop express going sixty miles an hour starts from Bustletown for Ironchester,
 * and another non-stop express going forty miles an hour starts at the same time from Ironchester for Bustletown.
 * How far apart are they exactly an hour before they meet?
 * As I have failed to find these cities on any map or in any gazetteer, I cannot state the distance between them,
 * so we will just assume that it is somewhere over $250$ miles.


 * If this little puzzle gives the reader much trouble he will certainly smile when he sees the answer.
