Cars A and B start from places a and b at the same time and drive towards each other. They meet at point c in 4 hours. The grounds start at the same time and go towards each other, and the meeting point is 8 kilometers away from the ground c. If the original speed ratio of A and B is 3:2, find the distance in kilometers between the two places.
甲、乙两车分别从a、b两地同时出发相向而行，4小时相遇在c地，如甲速度不变，乙每小时多走6千米，且甲、乙还是从a、b两地同时出发相向而行，则相遇点距c地8千米，若甲乙原来速度比是3：2，求甲乙两地相距多少千米．
