Question
UDAY Express is moving at 120 km/hr. The length of the UDAY Express is 150 meters. How long it will take to cross a platform of length 100 meters?
Speed of train in m/s = 120 x (5/18) = 300/18 = 50/3 m/s
The distance covered to cross the platform is equal to the sum of the length of the train and the length of the platform.
So, distance= 150+100 = 250 meters
Time = Distance/Speed
= 250 *3/100
=75/10 = 7.5 seconds
