A train is moving at a speed of 132 km/hr. If the length of the train is 110m, how long will it take to cross a railway platform 165m long?  Choose the correct choice: A) 8 sec B) 9 sec C) 7 1/2 sec D) 10 sec E) None
Speed of the train=(132*5/18)m/sec=(110/3)m/sec   Distance covered in passing the platform= (110+65)m=275m   Therefore, Time taken=(275*3/110)sec =7 1/2 Sec   Answer: Option 7 1/2 sec
