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 through the tunnel, from the moment the front enters, to the moment the rear emerges?
选项
答案
One minute
解析
列车需要运行的总长度为O.5+0.25=0.75miles=3/4miles,列车的速度为80mph,将其化成分钟为80/60=4/3mpm,因此需要的时间为3/4×4/3=lminute
