Member advised that some effort must be shown
Taking the age of Earth to be about 4 ✕ 109 years and assuming its orbital radius of 1.5 ✕ 1011 m has not changed and is circular, calculate the approximate total distance Earth has traveled since its birth (in a frame of reference stationary with respect to the Sun). It is asking for this answer in meters.
I do not have an equation here yet, I have read the chapter on this but I do not know where to begin with this problem.
