I had an interview for my first post-uni job today. One of the questions i was asked is shown below. Can any of you work out the answer?! Exciting! :)
A train travels from A to B. 1 hour through the journey there is a problem with the engine. The rest of the journey has to continue at 3/5 of the speed. The train arrived 2 hours later than it should have. The captain stated that if they had experienced the engine problem 50 miles later into the journey, they would have arrived 40 minutes earlier.
What is the distance, in miles, between A and B?
