Cars A and B start from A and B respectively at the same time and drive towards each other. When starting, the speed ratio of A and B is 5:4. After meeting, the speed of A increases by 20%, and the speed of B increases by 30%. , In this way, when A arrives at B, B is still 23 kilometers away from A, so how many kilometers is the distance between A and B?
甲、乙两车分别同时从A、B两地同时出发，相向而行，出发时，甲、乙的速度比是5：4，相遇以后，甲的速度提高20%，乙的速度提高30%，这样，当甲到达B地时，乙离A地还有23千米，那么A、B两地相距多少千米？
