A 160-meter-long train passes through a 2-kilometer-long subsea tunnel at a speed of 10 meters per second. Calculated from the time when the front of the train enters the tunnel to the time when the rear of the train leaves the tunnel, how many minutes does it take for the train to completely pass through the tunnel?
长160米的火车以每秒10米的速度穿越一个长2千米的海底隧道．从火车头入隧道到车尾离开隧道来计算，这列火车完全穿越隧道要多少分钟．
