Cars A and B start from two places AB at the same time and travel opposite each other. A travels 45 kilometers per hour and B travels 55 kilometers per hour. If A increases by 15 kilometers per hour and B increases by 5 kilometers per hour, the meeting time It can be (1/4) hour in advance, how many kilometers is the road between AB and AB?
甲乙两车同时从AB两地出发，相对而行，甲每小时行45千米，乙每小时行55千米，如果甲每小时增加15千米，乙每小时增加5千米，则相遇时间可提前(1/4)小时，AB两地的路是多少千米？
