The star system named Epsilon is a distance 10.8 light-years from the earth. The earth and Epsilon are assumed to be at rest relative to one another. Earth plans to launch a probe that will make the journey from earth to Epsilon at a constant velocity of 0.3c, where c=3.00x108 m/s is the speed of light. Define +x to be from earth to Epsilon. (A light-year is the distance traveled by light in 1 year)
