#MM(Mad Man) 박사는 XX연구소의 괴짜 연구원이다. 동료들을 골탕먹이기 좋아하니 조심하도록!#
MM이 타임머신을 만들었다. 타임머신은 시간 설정을 다이얼을 돌려서 하고, 현재 있는 시간에서 다이얼을 돌린 만큼 앞이나 뒤로 이동한다.
다이얼을 1도 돌릴때 마다 한 달을 이동할 수 있는데 다이얼이 고장 났다.
그래서 MM이 다이얼을 10도 돌리자 1990년 10월로 가 버렸다. 거기서 그리고리 파인만 이라는 사람을 만났는데 이름을 어디서 들어 본 것 같았다.
아무튼 다시 다이얼을 20도 돌렸는데 이번에는 1940년 10월로 가 버렸다. 이번에는 거기서 리처드 페렐만 이라는 사람을 만났는데 이 이름도 어디서 들어 본 것 같았다.
1) 이것 처리된 부분에서 잘못된 것을 고치시오
1)현재(2020년 10월)로 돌아가려면 다이얼을 몇 도 돌려야 할까?
2)다이얼을 1도 돌렸을때 시간이동이 얼마나 될까?
3)그렇다면 다이얼을 돌렸을때 한 달을 이동하고 싶다면 몇 도 돌려야 할까?
(단 다이얼을 돌린 각도를 어떤 식에 대입하면 식의 값이 이동한 개월 의 수 이다)
(추가: 3도 돌리면 192개월, 5도 돌리면 240개월 이동)
