The length of the bridge, which a train 130 metres long and travelling at 36 km/hr can cross in 45 seconds, is:
Options:	A) 320 m	B) 225 m	C) 245 m	D) 250 m	E) 240 m
Speed = [36X 5/18] m/sec = 10 m/sec   Time = 45 sec   Let the length of bridge be x metres.   Then, (130 + x)/45 = 10 =&gt; 130 + x = 450 =&gt; x = 320 m.   320 mNSWER:320 m
