Cars A and B start from AB at the same time at a speed of 4:3 and head towards each other. After meeting, car A speeds up by 20%, car B slows down by 20%, car A continues to move forward, and car B returns to point B. When car A exceeds 40 kilometers from point B, car B is 10 kilometers away from point B, and the distance between A and B How many kilometers? (no equation solution)
甲乙两车以4：3的速度同时从AB两地出发，相向而行．相遇后，甲车提速20%，乙车减速20%，甲车继续前进，乙车返回B地，当甲车超过B地40千米时，乙车距B地10千米，AB两地相距多少千米？(不用方程解答)
