Question

Train 'X' is moving at a speed of 108 km/h and takes 12 seconds to completely pass train 'Y', which is traveling in the opposite direction at 162 km/h. Additionally, train 'Y' is 180 meters longer than train 'X'. Determine the time required for the longer train to pass a stationary tree.

Q: Answer-Train 'X' is moving at a speed of 108 km/h and takes 12 seconds to completely pass train 'Y', which...

ATQ, Let the length of shorter train train X be x meter. So, length of the longer train train Y x 180 meters ATQ 162 108 518 x x 18012 Or, 75 12 2x 180 Or, 900 180 2x Or, 7202 x So, x 360 m Length of shorter train train X 360 m Length of longer train train Y 540 m So, time taken by the longer train to cross a tree 540162 518 54045 12 seconds
