Type 12: Train Crossing a Pole





Q. A 150 m long train is moving at a speed of 54 km/h. How much time will it take to cross a pole ?


Formula:


Time to Cross the Pole = Length of Train ÷ Speed of Train


                                  T = L/V

Where:



  • L = Length of train in metres

  • V = Speed of train in m/s


Solution:


Length of train = 150 m


Speed = 54 km/h


Convert km/h into m/s: 54 × 5/18 = 15 m/s


Therefore,T = 150/15 = 10 seconds 

Ans: 10 seconds
