Two passenger and freight vehicles depart from stations A and B at the same time and go towards each other. The speed ratio of the two vehicles at departure is 8:5. After meeting, the speed of the passenger vehicle decreases (3/8), and the speed of the freight vehicle increases by 25%. In this way, when the passenger vehicle arrives At point B, the truck is still 210 kilometers away from point A. How many kilometers are the two stations A and B?
客货两车分别从甲乙两站同时出发相向而行，出发时两车速度比是8：5，相遇后，客车的速度减少(3/8)，货车速度增加25%，这样，当客车到达乙地时，货车离甲地还有210千米．甲乙两站相距多少千米？
