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.
