From A to B, the express train takes 6 hours to arrive, and the slow train takes 10 hours to arrive. Now the two cars start from the two places at the same time and go towards each other. When they meet, the distance between the two cars is 120 kilometers from the midpoint. How many kilometers are the distance between A and B? ? (no equation solution)
从甲地到乙地，快车要6小时到达，慢车要10小时到达，现在两车从两地同时出发相向而行，相遇时，两车距中点120千米，甲乙两地相距多少千米？(不用方程解答)
