A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 240 m long?\nOptions:\n(A) 40 sec\n(B) 42 sec\n(C) 45 sec\n(D) 48 sec\n(E) 50 sec Hmmm, my stream of consciousness:
User
Speed = 45 * 5/18 = 25/2 m/sec\nTotal distance covered = 360 + 240 = 600 m\nRequired time = 600 * 2/25 = 48 sec So, the answer is (D).
