A and B start at 8:00 am at the same time from point A to point B, and walk for a while. At this time, A has traveled the whole distance (3/5), and B has traveled the whole distance (1/2). During the next journey, A keeps the original speed, and B travels 25 kilometers more per hour than before. As a result, both of them arrive at B at 2:00 pm at the same time. How many kilometers are there between A and B?
甲、乙两人同时于早上8：00出发从A地前往B地，走了一段时间，这时甲走了全程的(3/5)，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了25千米，结果二人同时于下午2：00到达B地，A、B两地相距多少千米？
