The distance between the east and the west is 9 kilometers. Xiaoming walks from east to west at 60 meters per minute. Xiaoli walks from west to east. Xiaohui rides a bicycle from east to west at 300 meters per minute. When Hui met Xiao Li, he turned back and rode eastward, when he met Xiao Ming, he turned back and rode westward, and when he met Xiao Li again, he turned back and rode eastward,... In this way, if Xiao Hui returns to meet Xiao Ming for the second time, the distance between Xiao Ming and Xiao Li is exactly 1 Kilometers, how many meters does Xiao Li walk per minute?
东西两地相距9千米，小明从东向西走，每分钟走60米，小莉从西向东走，小辉骑车从东向西走，每分钟300米，三人同时动身，途中小辉遇见小莉即折回向东骑，遇见小明又折回向西骑，再遇见小莉又折回向东骑，…这样往返，如果小辉第二次返回遇见小明时，小明与小莉相距恰好1千米，那么小莉每分钟走多少米．
