Cars A and B depart from stations A and B at the same time. After 7 hours, car A arrives at the midpoint, and car B is still 60 kilometers away from the midpoint. Given that the speed of car B is (2/3) that of car A, find the distance between stations A and B.
甲、乙两车同时A、B两站相对开出，7个小时后甲车到达中点，乙车离中点还有60千米．已知乙车的速度是甲车的(2/3)，求A、B两站的路程．
