둘레가 10km인 지구가 있습니다.
(단, 여기서 어떤 방향으로 간다는 뜻은, 처음 방향을 확인할 때 단 한번만 확인한 후, 그 방향으로 계속 간다는 뜻 입니다.)
A는 남쪽으로 1km , 동쪽으로 1km , 북쪽으로 1km를 갔더니
원래 출발한 곳으로 돌아왔습니다.
A와 같은 곳에서 동시에 출발한 B는
남쪽으로 7.5km , 동쪽으로 7.5km , 북쪽으로 7.5km를 갔습니다.
이때, A가 도착한 지점과 B가 도착한 지점의 거리는 얼마일까요?
(단, 약간의 오차가 있을 수 있으므로, 지구는 완벽한 구라고 가정하겠습니다.)
(풀이 필수)
