The installation of a gas pipeline can be completed in 144 days if the engineering team A works alone. Now, engineering team A started construction for 2 days, and then engineering team B joined in the construction together. After the two teams cooperated for 4 days, engineering team C was transferred to work together. After 8 days of joint construction, the three teams completed (1/3) of the entire project ), and after another 16 days, all the projects were completed (5/6). The rest of the project will be constructed by engineering team C alone, and how many days will it take to complete it.
安装一条煤气管道，若由甲工程队单独施工，144天可以完成．现在先由甲工程队施工2天，接着乙工程队加入一起施工，两队合作4天后，又调来丙工程队一起施工，三队联合施工8天后，共完成了全部工程的(1/3)，又过了16天，前后一共完成了全部工程的(5/6)．余下的工程由丙工程队单独施工，还要多少天才能全部完成．
