It takes 5 hours for car A to go from point A to point B, and the speed of car B to go from point B to point A is 5/8 of that of A. Now, cars A and B set off from points A and B at the same time, and drive towards each other , meet on the way and continue to move forward. Car A returns immediately after arriving at point B, and car B also returns immediately after arriving at point A. They meet again on the way. If the distance between the two meeting points is 66 kilometers, the distance between A and B How many kilometers?
甲车从A地到B地需要5小时，乙车从B地到A地，速度是甲的(5/8)，现在甲、乙二车分别从A、B两地同时出发，相向而行，在途中相遇后继续前进，甲车到B地后立即返回，乙车到A地后也立即返回，他们在途中又一次相遇，如果两次相遇点相距66千米，A、B两地相距多少千米？
