Run for your life...
Mr. Joy enjoys some risk and likes to explore the nearby area. In the beautiful surrounding there is a train track that goes through a mysterious tunnel. One fine morning Mr. Joy decided to take a walk through the tunnel. While Mr. Joy was 1/4 way on the tunnel, he hears the train whistle. A quick thinker Mr. Joy calculates that if he runs back he would just make it out of the tunnel before train gets in the tunnel and if he runs forward he will just make it out of the tunnel before train hits him. While Mr. Joy saved his life, he left you with a problem, how fast was this train travelling compare to Mr. Joy?
This is old school physics problem with all basic assumptions for this kind of puzzle. Assume Mr. Joy can run with same speed in both direction. He can accelerate to his top speed right away. Train barely misses him if he would run in either direction
Looking forward to see some solution(s)

The train makes it to the front of the tunnel, in the same amount of time it takes the person to travel a quarter of the tunnel. Hence if he continues running, by the time he travels another quarter tunnel (at the half way point), the train is at the entrance. Since he'll make it out of the tunnel just as the train does, that means the train travelled twice the distance in the same amount of times that it takes the man. Hence, the train travels twice a fast.
ReplyDeleteAmazing Skyrim. you solved it right. I may have to come up with some tougher one this time. Will come up with another one soon....keep watching...
ReplyDeleteI don't know how to even think like this... tell me how and put some more :)
