A train is 360 meter long is running at a speed of 52 km/hour. In what time will it pass a bridge of 140 meter length.	Choose the most appropriate option:
A) 24.62 seconds  B) 34.62 seconds  C) 44.62 seconds  D) 54.62 seconds  E) none of these

Rationale: "explanation : speed = 52 km / hr = 52 * ( 5 / 18 ) m / sec = 130 / 9 m / sec total distance = 360 + 140 = 500 meter time = distance / speed = 500 / 130 / 9 = 34.62 seconds answer : b"
Answer: B
