There is a straight road from A to B, which is divided into 3 sections. The length of the first section is twice the length of the third section. Car A travels on the first section of the road at a speed of 40 kilometers per hour. The speed on the second section of the road increased by 125%. Car B advances at a speed of 50 kilometers per hour on the third section, and increases the speed by 80% on the second section. Cars A and B set off from A and B at the same time and drive towards each other. After 1 hour and 20 minutes, Car A meets Car B oncoming from B at the (1/3) point of the second section of the road. ． How many kilometers are there between A and B?
从A到B有一条笔直的公路，共分为3段，第1段的长是第3段的长的2倍，甲汽车在第l段公路上以每小时40千米的速度行进，在第2段公路上速度提高了125%．乙汽车在第3段上以每小时50千米的速度前进，在第2段上把速度提高了80%．甲、乙两汽车分别从A、B同时出发，相向而行，1小时20分后，甲汽车在走了第2段公路的(1/3)处与从B地迎面而来的乙汽车相遇．那么A、B两地相距多少千米？
