The length of the bridge, which a train 130 meters long and travelling at 45 km/hr can cross in 30 seconds, is:	Pick one.
A) 200
B) 210
C) 245
D) 230
E) 265
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: Option 245
