A train running speed is 132 km/hr and the lenght of train is 110 meters. Calculate the time how long it will passed the platform. The length of platform is 165 meters.

A) 9.5 sec

B) 2.5 sec

C) 7.5 sec

D) 8 sec

Speed of train = (132 * 5/18)m/sec

= 110/3 m/sec

Totel covered distance = 110 + 165 = 275 m/sec

Time Taken = (275 * 3/110) sec

= 15/2 sec =7.5 sec
