Two passenger and freight vehicles drive from A to B at the same time, and return immediately when they arrive at B. When the truck travels 25% of the whole journey, the bus travels exactly 60 kilometers. At this speed, when the bus arrives at point B, the truck returns exactly 62.5% away from point A. When the truck arrives at A, how many kilometers is the passenger car away from A?
客货两车同时从甲地开往乙地，到达乙地立即返回．当货车行全程的25%时，客车正好行60千米，照这样的速度行驶，当客车到达乙地时，货车返回时离甲地正好是全程的62.5%．当货车到达甲地时，客车离甲地还有多少千米？
