The length of the bridge, which a train 110 metres long and travelling at 45 km/hr can cross in 30 seconds, is?	Choices
A) 10 m	B) 16 m	C) 245 m	D) 265 m	E) 27 m
Speed = [45 X 5/18] m/sec = [25/2] m/sec Time = 30 sec Let the length of bridge be x metres. Then, (130 + x)/30   = 25/2 =&gt; 2(110 + x) = 750 =&gt; x   = 265 m.   Answer: 265 m
