A train running at the speed of 50 km/hr crosses a pole in 18 seconds. Find the length of the train. Options:  A) 150  B) 188  C) 250  D) 288  E) 300

Rationale: "speed = 50 * ( 5 / 18 ) m / sec = 125 / 9 m / sec length of train ( distance ) = speed * time ( 125 / 9 ) * 18 = 250 meter answer : c"
Answer: C
