A train travelling at a speed of 75 mph enters a tunnel 2 —miles long. The length of the train is 1/4 mile. How long does it take for all of the train to pass through the tunnel, from the moment the front enters to the moment the rear emerges?
选项
A、2’12”
B、3’15”
C、2’20”
D、3’30"
答案
A
解析
火车的长度为1/4mile,隧道的长度为5/2miles,火车的速度为75mph,火车的长度加上隧道的长度再除以火车的速度,就可以得出走完这个隧道所用的时间。
