The speed ratio of the fast and slow cars is 3:2. If the speed of the two cars remains the same, and they start from A to B at the same time, when the fast car travels half of the way, the slow car is still 80 kilometers away from B. How many kilometers are there between A and B?
快慢两车的速度比是3：2，如果两车速度不变，同时从甲地出发去乙地，当快车行完全程的一半时，慢车距乙地还有80千米．甲乙两地相距多少千米？
