The train is one mile long, and the tunnel is also one mile long.

Time begin:

When the head of the train begins to enter the tunnel.

Time end:

When the tail of the train leaves the tunnel, or when the head of the train is one mile away from the tunnel.

The train has travelled two miles between "time begin" and "time end".

Can you figure out the time required?
