If teams A and B work together to complete a project, it takes exactly 24 days to complete it; if team B first works for 5 days, then team A comes to help, and after 10 days of joint work, the entire project is only half completed. May I ask: Team A alone How many days will it take to complete this project?
如果甲、乙两队合做一项工程，恰好24天完成；如果乙队先做5天，然后甲队来帮忙，又共同做了10天后，全部工程才完成了一半，请问：甲队单独完成这项工程需要多少天？
