and B travel towards each other from places A and B respectively, and meet at point C. (5/6) of the distance traveled by A is equal to (5/9) of the distance traveled by B, and (5/9) of the distance traveled by B is ( 2/7) is 30 meters longer than the distance traveled by A (2/5). Find the distance between A and B.
甲、乙两人分别从A、B两地相向而行，在C地相遇，甲所行路程的(5/6)与乙所行路程的(5/9)相等，乙所行路程的(2/7)比甲所行路程的(2/5)多30米，求AB两地的路程．
