A road repair team built a road. It was originally planned to repair 40 meters per day, and the repair was completed in 24 days. The actual repair was 180 meters in 3 days. Based on this calculation, how many days will it actually take to complete the road? (Use positive and negative ratios to solve)
一个修路队，修一条公路，原计划每天修40米，24天修完，实际3天修了180米，照这样计算，实际修完这条路需要多少天？(用正、反两种比例解)
