Cars A and B set off from AB at the same time and drive toward each other. After arriving at the starting point of the other side, they return immediately and meet for the second time at a distance of 60 kilometers from A. Given that the speed ratio of cars A and B is 3:2, find the distance between A and B.
甲、乙两车分别从AB两地同时出发，相向而行，到达对方出发地后，立即返回，在离A地60千米处第二次相遇．已知甲乙两车的速度比是3：2，求AB两地之间的距离．
