The length of the bridge, which a train 130 metres long and travelling at 45 km/hr can cross in 30 seconds, is?	Choose the correct choice from the following options: A) 288 B) 298 C) 245 D) 200 E) 212
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(130 + x) = 750 =&gt; x = 245 m. Answer: 245
