Cars A and B start from two places A and B at the same time and drive toward each other, and meet at a distance of 40 kilometers from the midpoint of the two places. Given that the speed ratio of A and B is 6:5, how many kilometers are there between A and B?
甲乙两车从A、B两地同时出发相向而行，在距两地中点40千米处相遇．已知甲乙速度比为6：5，A、B两地相距多少千米？
