Cars A and B start from A and B at the same time and go towards each other. When starting, the speed ratio of A and B is 4:3. After meeting, A's speed increases by 10%, and B's speed increases by 20%. , When A arrives at B, B is still 17 kilometers away from A, so how many kilometers is the distance between A and B?
甲、乙两车分别从A、B两地同时出发相向而行，出发时，甲和乙的速度比是4：3，相遇后，甲的速度增加10%，乙的速度增加20%，这样，当甲到达B地时，乙离A地还有17千米，那么A、B两地相距多少千米？
