Two cars drive from A to B at the same time, A car travels 80 kilometers per hour, and B travels 120 kilometers per hour. When car B travels 200 kilometers longer than car A, car A travels exactly 40% of the distance. Ask about the distance from point A to point B.
两辆汽车同时从A地开往B地，甲汽车每小时行80千米，乙汽车每小时行120千米．当乙汽车比甲汽车多行200千米时，甲汽车正好行了全程的40%．问A地到B地的路程．
