Cars A and B leave opposite places A and B at the same time, and continue to move forward after meeting each other. When the distance between the two cars is 70 kilometers, A has driven 75% of the whole journey, and the ratio of the distance between B and A to the distance traveled is 1:2, what is the distance between A and B?
甲乙两车同时从AB两地相对开出，相遇后继续前行，当两车又相距70千米时，甲行驶了全程的75%，乙离A地的路程与已行的路程的比为1：2，A、B两地的距离是多少？
