The Yirong ferry sails at a speed of 40 kilometers per hour, sailing downstream from point A to point B on odd-numbered days, and sailing upstream from point B to point A on even-numbered days. (The water speed is 24 kilometers per hour). On an odd-numbered day, when the ferry sailed to point C on the way, it lost power and had to let the boat drift to point B. The captain calculated that the time spent on that day was (43/ 18) times. On another even-numbered day, when the ferry sailed to point C on the way, it lost power again. During the drifting process, the maintenance personnel tried their best to repair it for an hour, and then the ship advanced to point A at 2 times the speed. The time taken by the original even-numbered days is exactly one second. What is the distance in miles between A and B?
怡荣号渡轮时速40千米，单数日由A地顺流航行到B地，双数日由B地逆流航行到A地．(水速为每小时24千米)有一单数日渡轮航行到途中的C地时，失去动力，只能任船漂流到B地，船长计得该日所用的时间为原单数日的(43/18)倍．另一双数日渡轮航行到途中的C地时，又失去动力，船在漂流过程中，维修人员全力抢修了1小时后船以2倍时速前进到A地，结果船长发现该日所用的时间与原双数日所用时间一秒不差．请问A、B两地的距离为多少千米？
