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) 328	B) 279	C) 245	D) 288	E) 211
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
