Two passenger and freight vehicles start from A and B at the same time and go towards each other. The speed ratio of the passenger and freight vehicles is 4:3. After meeting, the speed of the passenger vehicle decreases by 20%, and the speed of the freight vehicle increases (1/3). When the bus arrives at point B, the truck is still 25 kilometers away from point A. How many kilometers are there between A and B?
客货两车分别从A、B两地同时出发相向而行，客货两车的速度比是4：3，相遇后，客车速度减少20%，货车的速度增加(1/3)，这样当客车到达B地时，货车离A地还有25千米，AB两地相距多少千米？
