Cars A and B start from places A and B at the same time and drive toward each other. Car A travels 80 kilometers per hour, and car B travels 70 kilometers per hour. When A travels to (2/5) of the whole journey, Car B is still 36 kilometers away from the midpoint. How many miles is the distance between A and B?
甲、乙两车分别从A、B两地同时出发，相向而行，甲车每小时行80千米，乙车每小时行70千米，当甲行至全程的(2/5)时，乙车距中点还有36千米．A、B两地的路程是多少千米？
