Two trains A and B travel from A to B and C in opposite directions at the same time. It is known that the distance between A and B is (9/10) of the distance between A and C. When car A travels 220 kilometers, the ratio of the distance traveled by car B to the remaining distance is 3:5. At this time, the distances from the two trains to the destination are equal. Find the distance between places A and C.
甲、乙两列火车同时从A地向相反的方向B地和C地行驶，已知A，B之间的路程是A，C之间路程的(9/10)．当甲车行驶220千米时，乙车行驶的路程与剩下的路程的比是3：5，这时两列火车离目的地的路程相等，求A、C两地之间的路程．
