# Interview Question

Hey people.

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?

There are 4 people on a walk. They get to an old rickety bridge that they have to cross. It is only safe for 2 of them to cross at a time. It is also dark and a torch needs to be carried accross and brought back for the next crossing. One of the people is injured and will take 10 minutes to cross the bridge, another will take 4 minutes to cross the bridge, another 2 minutes and the 4th person takes 1 minute.

what is the shortest time that they can all cross the bridge?

10 mins + 1 min return on first leg

4 mins + 1 min return second

2 mins no return for third leg

18 minutes:thumbsup:

which is the answer they are after?

96 / 2 = 48

1/4 of 48 = 12

48 + 12 = 60

You can save more time if the 10 and 4 minute people go together :-)

2 & 1 cross: 2 min

1 returns: 1 min

10 & 4 cross: 10 min

2 returns: 2 min

2 & 1 cross: 2 min

Total: 17 min

It doesn't even say the Captain was driving the train. He could of just been a passenger.
