Measured on a map with a scale of 1:2000000, the length of the railway between A and B is 6 cm. The length of the two trains is 6 cm from the railway between A and B. The two trains depart from A and B at the same time. , It is known that the car traveling from place A travels 125 kilometers per hour, and the car traveling from place B travels 115 kilometers per hour. How many hours will they meet?
在比例尺是1：2000000的地图上量得甲，乙两地间的铁路长6厘米，两列火车分别从甲乙两地间的铁路长6厘米，两列火车分别从甲乙两地同时相对开出，已知从甲地开出的车每小时行125千米，从乙地开出的车每小时行115千米，几小时后相遇？
