The length of the bridge, which a train 110 metres long and travelling at 45 km/hr can cross in 30 seconds, is? Options:	A) 255	B) 265	C) 245	D) 277	E) 211
Speed = [45 X 5/18] m/sec = [25/2] m/sec Time = 30 sec Let the length of bridge be x metres. Then, (110 + x)/30 = 25/2 =&gt; 2(110 + x) = 750 =&gt; x = 265 m.   Answer:265
