I had a noon appointment in town and decided after a leisurely breakfast to get an appropriate train for the precisely 19 mile rail journey.
As the train drew out of the station I noticed on my very accurate watch that the departure was exactly on time.
As we arrived at the London terminus I noticed that the hour and minute hands on my watch were exactly coincident. I calculated that the train have averaged a whole number of miles per hour for my journey.
What time did the train depart and what was its average speed?
