Two people, A and B, start from A to B at the same time. When A walked the whole distance (3/5), B walked the whole distance (1/2). During the rest of the journey, A maintains the original speed, and B travels 25 kilometers more per hour than before. As a result, A and B arrive at B at the same time. The whole journey took 6 hours. How many kilometers are there between A and B?
甲、乙两人同时从A地出发前往B地．当甲走了全程的(3/5)时，乙走了全程的(1/2)．在剩下的路程中，甲保持原速，乙每小时比原来多行25千米，结果甲、乙两人同时到达B地．甲行全程用了6小时．A、B两地相距多少千米？
