Hello, Jake. Thanks for your letter! As soon as I have received it I start writing to you. Our teachers also discuss the issues of choosing our future job in the lessons. As for me I am interested in a job of lawyer, because it is interesting and I like helping people. I agree with that we have to choose our future occupation according to our likes and dislikes. And we also must take into consideration our personal qualities. For example, if you don’t like children you’d better stop thinking about becoming a teacher. By the way, Why are you going to take a gap year before going to the university? What are you going to do? Are you going to travel?
Sorry. I have to go. I must help my mother. Best regards, ……………...

ответ: Скорость звезды превышала бы скорость света в ≈ 242 раза
Объяснение: Если расстояние (S) до звезды равно указанному в вопросе, то длина орбиты звезды была бы L = 2πS = 2*3,141159*10^15км.
Такое расстояние звезда пролетала бы за одни сутки. В сутках содержится Tс = 24*60*60 = 86400 = 8,64*10^4 секунд.
Следовательно скорость звезды была бы
U = L/Tc = 2*3,141159*10^15/8,64*10^4 = 7,2722*10^10 м/с
Скорость света 3*10^8 м/с. Значит, скорость звезды была бы больше скорости света в 7,2722*10^10/3*10^8 ≈ 242 раза
