and B set off from A and B at the same time, and meet somewhere after 4 hours. If A travels 1.5 kilometers more per hour, and B starts 24 minutes earlier than A, they will still be here when they meet , if A departs 48 minutes later than B, and B travels 2.5 kilometers less per hour, and can still meet here, then how many kilometers is the distance between A and B?
甲、乙两人分别从A、B两地同时出发，4小时后在某处相遇，如果甲每小时多走了1.5千米，而乙比甲提前24分钟出发，则相遇时仍在此处，如果甲比乙晚48分钟出发，乙每小时少走2.5千米，也能在此相遇，那么A、B两地之间相距多少千米？
