함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.
[문장제 문제&개념응용] ( E ti ) 지구멸망

때는 3057년, 지구는 탐욕과 부정부패, 환경오염으로 멸망했다,
살아남은 소수의 사람들은 멸망한 지구를 버리고, 인간이 살기 적합한 2002 Tc302R로 이동했다.
2022년으로부터 많은 시간이 지난 지금은 지구의 모든 국가들이 과학 경제 강국으로 변하였다.
그리하여 그들은 qwe143이라는 행성간의 이동수단을 개발 하였는데,
qwe143은 초속 80000km이다.
1: qwe143을 사용해서 이동하던 중, 초속 100000km의 소행성이 60000km 앞에 있다,
그럼 몇초 후에 qwe143과 소행성의 위치는 일치하는가?
2: 2002 Tc302R로 가던 중, qwe143 밖으로 사람 19명, 동물 28마리 중, 사람 1명을 우주로 보네야 하는 일이 생겼다.
지금 우주선이 방전이라고 할때, 최소 ( 손전등 없음 ) 몇명 ( 마리 )을 밖으로 던져야 사람이 나오는가?

쉽게 말해, "최소 몇번 빼야 사람이 나오는가?" 입니다,

소행성이 이동수단쪽으로 오고 있나요
아니면 소행성과 이동수단이 같은방향으로 가고 있나요?
