(캐릭터와 줄거리는 이상한 여행 1편을 참고해주세요)
영국에 도착한 아르,키메,데스는 두팀으로 나뉘어 다른 지역으로 여행을 떠나기로 했다. 그러고는 두 지역과 런던의 무게중심에서 만나자고 했다.
지도가 다음과 같을때 무게중심은 얼마이고, 그 좌표가 바다일까 육지일까?
더블린(-200,100)/런던(0,0)/에든버러(-40, 290)
| 세로선(왼쪽) |
세로선(오른쪽) |
가로선(위쪽) |
가로선(아래쪽) |
| x=-120 |
x=-40 |
y=195 |
y=100 |
위 표와 좌표를 참고해주세요.
(그림 잘 못 그리는건 이해 부탁드려요)
(풀이 필수)
