Give a number that represents the answer in Number?

Every day, Jack arrives at the train station from work at 5 pm. His wife leaves home in her car to meet him there at exactly 5 pm, and drives him home. One day, Jack gets to the station an hour early, and starts walking home, until his wife meets him on the road. They get home 30 minutes earlier than usual. How long was he walking? Distances are unspecified. Speeds are unspecified, but constant.

¾h since: he is one hour early before his wife arrives at the train station so 1 hour - half an hour early / 2 ways = ¼
