The passenger car and the truck depart from A and B oppositely at the same time, and meet each other in 5 hours. After the meeting, the two cars still move forward at the same speed. When the distance between them is 80KM, the truck travels the whole distance (13/24), and the bus travels the whole distance. (5/8). How many hours does it take for the bus to complete the journey? (results expressed in fractions)
客车、货车同时从A、B两地相对开出，5小时相遇，相遇后两车仍按原速前进，当它们相距80KM时，货车行了全程的(13/24)，客车行了全程的(5/8)．客车行完全程需要多少个小时？(结果用分数表示)
