Every Saturday the husband stays at home and the wife goes to her office. The office is over at five o'clock. The husband always arrives at the office at five o'clock sharp to pick up the wife and drive her home. One Saturday, the office ends an hour early. The wife starts walking home. Eventually she meets her husband and is picked up. She is home 20 minutes earlier than usual. How long did the wife walk before she was picked up by the husband?
