Question: As Mars orbits the sun in its elliptical orbit, its distance of closest approach to the center of the sun (at perihelion) is 2067 X

As Mars orbits the sun in its elliptical orbit, its distance of closest approach to the center of the sun (at perihelion) is 2067 X 1011 m, and its maximum distance from the center of the sun (at aphelion) is 2.492 X 1011 m. If the orbital speed of Mars at aphelion is 2.198 X 10 m/s, what is its orbital speed at perihelion? (You can ignore the influence of the other planets.)
