A and B start from A and B respectively at the same time. If two people are walking toward each other, they meet after 3 minutes. If two people are walking in the same direction, A catches up with B after 13 minutes. If B walks 25 meters per minute, what is the distance between A and B in meters?
甲、乙两人分别从A、B两地同时出发．如果两人相向而行，经过3分钟两人相遇．如果两人同向而行，经过13分钟甲追上乙．已知乙每分钟走25米，则A、B两地的距离是多少米．
