Cars A and B respectively depart from AB and AB at the same time. Car A travels 57 kilometers per hour and arrives at the midpoint of AB two hours earlier (1/3) hour than car B. When car B reaches the midpoint, car A drives forward at the same time and arrives at point C between AB and AB. At this time, the ratio of the distance between A and B to the whole journey is 3:8. How many kilometers are there between AB and AB?
甲乙两车分别从AB两地同时相对开出．甲车每小时行57千米，比乙车早(1/3)小时到AB两地的中点，当乙车到达中点时，甲车同时向前行驶到达AB两地间的C地，这时甲车到B地的路程和全程的比是3：8，AB两地相距多少千米？
