Cars A and B drive oppositely from places A and B at the same time. The first meeting is 200 kilometers away from place A, and then they each continue to drive at their original speed. The distance from A to the second meeting accounts for 75% of the total length between A and B. How many miles is the distance between A and B?
甲、乙两辆汽车同时从A、B两地相对开出，第一次相遇离A地有200千米，然后各自按原速继续行驶，分别到达对方出发地后立即沿原路返回．第二次相遇时离A地距离占A、B两站间全长的75%．A、B两地间的路程长多少千米？
