A and B set off from A and B at the same time respectively, and they meet at the midpoint after 6 hours. If A delays his departure by 1 hour, and B travels 4 kilometers less per hour, the two still meet at the midpoint. May I ask: A How many kilometers are there between B and B?
甲、乙两人分别从A、B两地同时出发，6小时后相遇在中点，如果甲延迟1小时出发，乙每小时少走4千米，两人仍在中点相遇，请问：甲、乙两地相距多少千米？
