A marketer takes a train from City A to City B. When the train was halfway through the journey, the salesman fell asleep. When he woke up, he looked at the sign and found that the remaining distance was (1/3) of the distance traveled by the train before he fell asleep. Think about it, what fraction of the whole journey has the train traveled?
