On a map with a scale of 1:5000000, the length of the railway between A and B is 6 cm. If two trains A and B depart from two places at the same time, train A travels 96 kilometers per hour, and train B travels 104 kilometers per hour, how many hours will the two trains meet.
在比例尺是1：5000000的地图上量得A、B两地之间的铁路长为6厘米．如果甲、乙两列火车同时从两地出发，甲车每小时行96千米，乙车每小时行104千米，多少小时后两列火车能相遇．

<output>1/5_000_000 = around 0</output>

<gadget id="calculator">96 + 104</gadget>
<output>200</output>

<gadget id="calculator">6 / (1/5_000_000) / 100_000 / 200</gadget>
<output>3/2 = around 1.5</output>

<result>3/2 = around 1.5</result>
