i know that one, i got it right away, and what is funny about this is you can change every variable, and as long as each variable uses the same number it always equals two

if its a mile long tunnel wuldnt it take 1 minute

The front of the train will reach the end of the tunnel a minute after it enters. But the end of the train is still in the entrance of the tunnel (coz the train is 1-mile long). So it will take another minute for the end of the train to get out of the tunnel.
