The passenger car and the freight car depart from two stations A and B at the same time and meet each other 5 hours later. After the meeting, the two vehicles still move forward at the original speed. When they are 196 kilometers apart, the truck has traveled 80% of the whole journey, and the ratio of the distance traveled by the bus to the distance not traveled is 3:2. Find the distance between stations A and B.
客车和货车分别从A、B两站同时相向开出，5小时后相遇．相遇后，两车仍按原速度前进，当它们相距196千米时，货车行了全程的80%，客车已行的路程与未行的路程比是3：2．求A、B两站间的路程．
