The length of the bridge, which a train 160 meters long and travelling at 45 km/hr can cross in 30 seconds, is? Choose the correct choice from the following options:
A) 328  B) 279  C) 215  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, (160 + X)/30 = 25/2 ==&gt; 2(160 + X) = 750 ==&gt; X = 215 m.Answer: 215
