Henry Ernest Dudeney/Modern Puzzles/41 - The Damaged Engine

by : $41$

 * The Damaged Engine
 * We were going by train from Anglechester to Clinkerton, and an hour after starting some accident happened to the engine.


 * We had to continue the journey at $\tfrac 3 5$ of the former speed, and it made us $2$ hours late at Clinkerton,
 * and the driver said that if only the accident had happened $50$ miles farther on the train would have arrived $40$ minutes sooner.


 * Can you tell from that statement just how far it is from Anglechester to Clinkerton?
