수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
어느 뱃사공 3명과 짐 4개가 강을 건너려고 한다.
강을 건너려면 배를 타야하는데 배는 60kg~140kg에서만 작동하고, 짐이 있는 곳에는 반드시 뱃사공이 있어야 한다.
또 배에는 최소 한명의 뱃사공이 있어야 한다.
짐의 무게는 각각 14, 16, 39, 40(단위 kg)이고, 뱃사공의 몸무게는 각각 47, 63, 77(단위 kg)일때, 배는 최소 몇번을 움직여야 할까?
(풀이까지 남겨주세요)

뭔가 뱃사공이 아니라 항해사가 필요한 배일것 같네요..?
