A train running at the speed of 50 km/hr crosses a pole in 18 seconds. Find the length of the train.\nOptions:\n(A) 150\n(B) 188\n(C) 250\n(D) 288\n(E) 300
Step-by-step reasoning:
(C)
Speed = 50*(5/18) m/sec = 125/9 m/sec\nLength of Train (Distance) = Speed * Time\n(125/9) * 18 = 250 meter.

Final answer: (C)
