A train 650 m long is running at a speed of 81 km/hr. In what time will it pass a bridge 340 m long?\nOptions:\n(A) 42\n(B) 43\n(C) 44\n(D) 45\n(E) 46 Hmmm, my stream of consciousness:

Speed = 81 * 5/18 = 45/2 m/sec\nTotal distance covered = 650 + 340 = 990 m\nRequired time = 990 * 2/45 = 44 se So, the answer is (C).
