A and B set off from A and B at the same time and walk toward each other, and meet at C after 4 hours. If A's speed remains unchanged, B travels 6 kilometers more per hour, and A and B still start from A and B at the same time and go toward each other, then the meeting point is 8 kilometers away from point C; if A and B's original speed is The ratio is 4:3, what is the original speed of A in kilometers per hour?
甲乙两人分别从A、B两地同时出发相向而行，4小时后相遇在C地．如果甲速度不变，乙每小时多行6千米，且甲、乙还是从A、B两地同时出发相向而行，则相遇地点距C点8千米；若甲、乙原来的速度的比是4：3，问甲原来的速度是每小时多少千米？
