Mad Ade's Train Accident
Mad Ade was going by train from Kebabchester to Penistone, and an hour after setting off an accident happened to the train.
Despite this the train had to continue the journey at three-fifths of the former speed. It made Mad Ade two hours late at Penistone, and the driver said that if only the accident had happened fifty miles farther on the train would have arrived forty minutes sooner. Can you tell from that statement just how far it is from Kebabchester to Penistone?
