Two cars, A and B, leave opposite places A and B respectively. Car A travels 68 kilometers per hour, and car B travels 50 kilometers per hour. After the two cars meet, they continue to move forward at the same speed. Cars A and B arrive at places B and A respectively and return immediately. When the two cars meet again, car A travels 378 kilometers longer than car B. How many miles is the distance between A and B?
甲、乙两车分别从A、B两地相对开出，甲车每小时行68千米，乙车每小时行50千米．两车相遇后仍以原来速度继续前进，甲、乙两车分别到达B、A两地之后立即返回，两车再次相遇时，甲车比乙车多行了378千米．则甲、乙两地相距多少千米？
