어떤 학교에서 학생 12명이 놀이공원으로 체험학습을 가려고 한다.
하지만 멍청한 선생님의 실수로 6인승 카X발을 하나밖에 빌리지 못하여서
놀이공원까지 6명이 걸어가야되는 불상사가 생기고 말았다.
놀이공원은 학교에서 56km 떨어져 있고,
차는 시속 60으로, 학생은 시속 6으로 걸어간다.
차가 가면서 운전자가 걷고 있는 6명의 학생들이 안쓰러웠는지 현재 타고 있는 6명의 학생을 쫓아낸... 다음
그들은 시속 6으로 목적지를 향해 걸어가고, 차는 다시 방향을 틀어 걸어오고 있는 나머지 6명과 만나 다시 태워줘 놀이공원에 갔더니
차와 사람이 동시에 도착해 있었다.
이때, 운전수가 먼저 차에 있었던 학생 6명을 내쫓을 때가
차가 학교에서 출발한지 몇km이 지났을 때 였을까?
답이 소수로 나오면 정수로 반올림해주세요.
