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 answer:
A) 200 m B) 225 m C) 245 m D) 250 m E) 300 m
Explanation:   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   2(130 + x) = 750   x = 245 m.   ANSWER IS 245 m
