In a certain competition, 10 first prizes and 20 second prizes were originally scheduled. Now the last four first prizes are adjusted to second prizes. In this way, the average score of the first prize is increased by 4 points, and the average score of the second prize is increased by 1 point. So, how much more is the average score of the first prize than the average score of the second prize?
某次比赛原定一等奖10人，二等奖20人，现将一等奖后四名调整为二等奖，这样一等奖平均分提高4分，二等奖平均分提高1分，那么，原来一等奖平均分比二等奖平均分多几分？
