The railway from Dalian to Beijing is about 935 kilometers long. A train of freight trains travels from Dalian to Beijing at a speed of 90 km/h; a train of passenger cars departs from Beijing to Dalian at the same time at a speed of 80 km/h. How long did it take for the two cars to meet? How many kilometers is the distance from the meeting place to Beijing? (First write out the equivalent relationship, and then use the method of column equation to solve it)
大连到北京的铁路长约935千米．一列货车从大连开往北京，速度是90千米/时；一列客车同时从北京开往大连，速度是80千米/时．经过几时两车相遇？相遇地点距北京的路程是多少千米？(先写出等量关系式，再用列方程的方法解答)
