Question 892391
A train which is 100 meters long is traveling at a speed of 90km/hour. How many seconds will it take for this train to pass completely through a 300 meter tunnel
***
travel time=distance/speed
distance=100+300=400 m
{{{travel time=(90km/hr)/400m*(1000m/km)*(hr/3600sec)=((90*1000)/(400*3600))sec=(.0625) sec}}}
