Two transport teams, A and B, respectively contracted to transport two piles of the same cargo. It was originally planned that team A would complete the work two days earlier than team B, but five days later it encountered continuous rain. Or was it reduced by 40% and 25% respectively, and as a result, the two teams finished shipping at the same time, so how long did it take Team A to complete the task?
甲乙两个运输队分别承包两堆同样货物的运输工作，原计划甲队比乙队早两天完成，但5天后遇上连雨天，尽管两队冒雨抢运，但是甲乙两队的工作效率还是分别降低了40%和25%，结果两队同时运完，那么原计划甲队完成任务需要的是天？
