On a map with a scale of 1:10000000, the distance between A and B is 2.4 cm. Cars A and B start from two places at the same time and drive towards each other. It is known that the speed of car A is 48 kilometers per hour, and the speed ratio of the two cars is 3:2. How many hours later will the two cars meet?
在比例尺是1：10000000的地图上，量得A、B两地的距离是2.4厘米．甲乙两车同时从两地出发，相向而行，已知甲车的速度是每小时48千米，两车的速度比是3：2．两车几小时后相遇？
