Two cars A and B leave from two places A and B at the same time, and B travels 10% of the whole journey every hour. When reaching the midpoint, car A continues to drive forward for 25 kilometers to reach point C. How many miles is the distance between A and B?
甲、乙两辆汽车分别从AB两地同时相对开出，乙每小时行全程的10%，甲车比乙车早(1/3)小时到达A、B两地的中点，当乙车到达中点时，甲车又继续向前行驶了25千米到达C点．AB两地相距多少千米？
