From A to B, Xiaohong walked to the midpoint in 15 minutes (midpoint: middle), and Xiaolin could walk the whole distance in 20 minutes (4/5). If two people start from opposite places, after 10 minutes, what percentage of the distance is the distance between them?
从A地到B地，小红15分钟走到中点(中点：中间)，小林20分钟能走全程的(4/5)．如果2人从两地相对出发，经过10分钟，两人相距的路程占全程的几分之几？
