A road is built by two people, A and B. If it is sunny, it will take 12 days for team A and 15 days for team B to complete it alone. However, it has been raining from the beginning to the end of the work, so team A will repair 10 meters less every day, and team B will repair 12 meters less every day. As a result, it took 10 days to complete Task. Question: How long is this road in meters?
一条公路由甲、乙两人合作修筑．若是晴天，单独完成，甲队要12天，乙队要15天，可是从开工到结束一直下雨，因此甲队每天少修10米，乙队每天少修12米，结果用了10天才完成任务．问：这条公路长多少米？
