问题
A train traveling at a speed of 80 mph enters a tunnel that is 0.5 miles long.The length of the train is 0.25 miles, How long does it take for all of the train to pass the tunnel, from the moment the front enters, to the moment the rear emerges?
选项
答案
9/16 minute.
解析
分析题目 可知,列车需要运行的总长度为0.5 +0.25 =0.75 miles=3/4 miles,列车的速度为80 mph, 将其转换成分钟80/60 =4/3 mpm,所以需要的时间为3/4 +4/3 =9/16 minute。
