Let's assume that the period of circulation is 27 days and eight hours, then: T=27d8h=27*24+8h=656h=2361600s=23,616*10^5s\\ R=384\ 400km=38,44*10^4km=38,44*10^7m\\\\ v=\omega R\\\\ \omega=\frac{2\pi}{T}\\\\ v=\frac{2\pi R}{T}\\\\ v=\frac{2*3,14*38,44*10^7}{23,616*10^5}\\\\ v=\frac{241,4032*10^7}{23,616*10^5}\\\\ v=10,22*10^2\frac{m}{s}=1022\frac{m}{s}=1,022\frac{km}{s}
