Cars A and B set off from places A and B at the same time, and drive towards each other. After meeting, the two cars continue to move forward. When car A travels the whole distance (5/9) and car B travels the whole distance (5/9), the distance between the two cars is 34 kilometers. Find the distance between A and B.
甲、乙两车分別从A、B两地同时出发，相向而行，相遇后两车继续前进．当甲车行了全程的(5/9)，乙车行了全程的(5/9)时，两车相距34千米．求A、B两地间的距离．
