The length of the bridge, which a train 130 m long and traveling at 45 km/hr can cross in 30 sec is?	Choose the correct choice from the following
A) 25/5
B) 25/3
C) 25/2
D) 25/1
E) 25/9
Speed = 45 * 5/18 = 25/2 m/sec.   Time = 30 sec   Let the length of bridge be x meters.   Then, (130 + x)/30 = 25/2   x = 245 m.Answer:25/2
