The sum of the speeds of cars A and B is 130 km, and the speed ratio between car A and car B is only 8:5. Now the two cars start from point C at the same time, and when they go backwards, they arrive at points A and B at the same time. , Car B returns immediately from point B at the same speed, when car B travels for 30 minutes, then car A starts to return from point A, and increases the speed by 25%, so that the two cars return to point C at the same time, find A, How many miles is B's distance?
甲、乙两车的速度和是130千米，甲车与乙车的速度只比是8：5，现在两车同时从C地出发，背向而行恰好是同时分别到达A、B两地，乙车从B地原速立即返回，当乙车行了30分钟后，这时甲车从A地开始返回，并将速度提高25%，这样两车又同时返回到C地，求A、B的路程是多少千米？
