Xiaojun's father takes 30 minutes to walk from home to the railway station. What's the latest time for him to leave home so that he won't miss the train (stop checking tickets five minutes before driving),

1. The total time from Tianjin to Jinan is 17:30-13:30 = 4 hours, so the distance is 230 × 4 = 920 km
2. If you have to walk for 30 minutes and stop checking in five minutes before driving, Xiaojun's father should start from home at 12:55 (13:30-00:30-00:05)
