Henry Ernest Dudeney/Puzzles and Curious Problems/65 - The Pedestrian Passenger

by : $65$

 * The Pedestrian Passenger
 * A train is travelling at the rate of $60$ miles per hour.
 * A passenger at the back of the train wishes to walk to the front along the corridor,
 * and in doing so walks at the rate of three miles per hour.
 * At what rate is the man travelling over the permanent way?


 * We will not involve ourselves here in quibbles and difficulties,
 * similar to Zeno's paradox of the arrow, and Einstein's theory of relativity,
 * but deal with the matter in the simple sense of motion in reference to the permanent way.
