The length of the bridge, which a train 110 meters long and travelling at 45 km/hr can cross in 30 seconds, is? Choose the most appropriate option
A) 265  B) 288  C) 245  D) 776  E) 232
Speed = (45 * 5/18) m/sec = (25/2) m/sec. Time = 30 sec. Let the length of bridge be x meters. Then, (110 + X)/30 = 25/2 ==&gt; 2(110 + X) = 750 ==&gt; X   = 265 m.   265nswer:265
