In the "Concrete Road Project for Every Village", a village plans to pour 4244 meters of cement pavement in 120 days. The actual pouring time is 1/5 earlier than the plan. How much is the actual work efficiency higher than the plan?
在"村村通水泥路工程"中，某村计划120天浇注水泥路面4244米，实际浇注的时间比计划提前(1/5)，实际工作效率比计划提高百分之几？
