Two cars, A and B, drive from point A to point B at the same time. When car A travels (1/3) of the whole journey, B is still 240 kilometers away from point B. When A arrives at point B, B only travels the full distance ( 3/5), how many kilometers is the distance between AB and AB?
甲乙两车同时从A地驶向B地，当甲车行了全程的(1/3)时，乙离B地还有240千米，当甲到达B地时，乙只行了全程的(3/5)，AB两地相距多少千米？
