Uncle Li led the engineering team to repair a road. They repaired 25% of the total length of the road in the first week, and the remaining (2/3) was 180 meters longer in the second week. At this time, there are still 720 meters left to be repaired. Uncle Li wants to know how many meters is the total length of this road?
