A train running at the speed of 60 km/hr crosses a pole in 30 seconds. What is the length of the train?	Choose the most appropriate option.
A) 500 m  B) 620 m  C) 872 m  D) 150 m  E) 765 m

Rationale: "speed = ( 60 * 5 / 18 ) m / sec = ( 50 / 3 ) m / sec length of the train = ( speed x time ) = ( 50 / 3 * 30 ) m = 500 m . answer : a"
Answer: A
