You can put this solution on YOUR website! A train is 90 meters long and enters a 310 meter long tunnel at a speed of 4 m/s . how much time in seconds will the train take to pass completely through the tunnel ?
length of train 90 meters
length of tunnel 310 meters
if the train has to get out completely from the tunnel it has to travel 310 +90 meters
=400 meters
speed of train = 4 m /sec
time taken = distance / speed
= 400/4
= 100 seconds
train will take 100 sconds.
