The length of the bridge, which a train 130 meters long and travelling at 45 km/hr can cross in 30 seconds, is?	Pick:
A) 266	B) 288	C) 245	D) 776	E) 232
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
