Cars A and B leave opposite places A and B at the same time, and continue to move forward after meeting. When the distance between the two cars is 70 kilometers, A has driven 75% of the entire distance, and the ratio of the distance between B and A to the distance traveled is 1:2. How many kilometers are there between A and B?
甲、乙两车同时从A、B两地相对开出，相遇后继续前行．当两车又相距70千米时，甲行驶了全路程的75%，乙离A地路程与已行路程的比为1：2．A、B两地相距多少千米？
