Answers
A) 230 meters
B) 235 meters
C) 240 meters
D) 245 meters
E) None of these
ExplanaƟon:   Let the length of bridge is X [as always we do :)]   Speed of train is = 45*(5/18) m/sec = 25/2 m/sec   Time = 30 seconds   Total distance = 130+x   We know Speed = distance/Ɵme   so,   130+x30=252=&gt;2(130+x)=750x=245 meters   So length of the bridge is 245 meters   Answer:245 meters
