Two passenger and freight trains depart from places A and B at the same time, respectively, and drive toward each other. The speed ratio of the passenger car and the truck is 6:5 at departure; after meeting, the speed of the passenger car decreases by 20%, and the speed of the truck increases by 20%. In this way, when the truck arrives at point A, the bus is still 10 kilometers away from point B. How many kilometers are there between A and B?
客、货两车分别从甲、乙两地同时出发，相向而行．出发时客车、货车的速度比是6：5；相遇后，客车的速度减少20%，货车的速度增加20%．这样，当货车到达甲地时，客车离乙地还有10千米．甲、乙两地相距多少千米？
