The length of the bridge, which a train 130 meters long and travelling at 45 km/hr can cross in 30 seconds, is?	Choose the correct choice from the following answers
A) 267 m	B) 256 m	C) 245 m	D) 627 m	E) 167 m
Speed   = (45 * 5/18) m/sec = (25/2) m/sec. Time   = 30 sec. Let the length of bridge be x meters. Then, (130 + X)/30 = 25/2 ==&gt; 2(130 + X)   = 750 ==&gt; X   = 245 m.   Answer: 245 m
