The length of the bridge, which a train 130 meters long and travelling at 45 km/hr can cross in 30 seconds, is?
Options.
A) 277	B) 237	C) 245	D) 376	E) 368
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
