You are on the planet Romulus orbiting the star Eisn, and you observe that Romulus laps another planet S'latas on average every 3.50 of its orbital periods (call it a R-year: 1 R-year = 210.4 Earth days). During this time, calculate how many degrees S'latas moves along its orbit and then how many degrees/R-year S'latas sweeps out so that you can answer: to two significant digits, how many Earth days S'latas to go around Eisn?
