The work-efficiency ratio of two engineering teams, A and B, is 4:3, and the two engineering teams repair a section of road with the same length at the same time. When Team A repairs 480m, 25% of Team B's completion of the task is 40m less. How many meters are the roads that teams A and B need to build?
甲、乙两工程队的工效比是4：3，两工程队同时分别修一段同样长的公路．当甲队修480m时，乙队完成任务的25%少40m．甲、乙两队要修的公路各是多少米？
