Cars A and B set off from places A and B facing each other. When car B travels 96km, car A starts. When the two cars meet, the ratio of the distance between places A and B is 3:4. Given that the speed ratio of cars A and B is 5:4, find the distance between A and B.
甲、乙两车分别从A、B两地相向出发，乙车开出96km时，甲车出发，两车相遇时离A、B两地的距离比是3：4．已知甲、乙两车的速度比是5：4，求A、B两地间的距离．
