A train running at the speed of 58 km/hr crosses a pole in 9 seconds. Find the length of the train? Choose one:	A) 145	B) 272	C) 278	D) 277	E) 112

Rationale: "speed = 58 * ( 5 / 18 ) m / sec = 145 / 9 m / sec length of train ( distance ) = speed * time ( 145 / 9 ) * 9 = 145 meter answer : a"
Answer: A
