Earth orbits the sun in an elliptical pattern. The equation of Earth's path is (x+2.5) ^2/22350.25 + y^2/22344=1 where the measurements represent millions of kilometers. The sun is located at the focus whose coordinate is (0,0). In January, Earth is located at one of the vertices, which is 147 million kilometers from the sun. Determine Earth's distance from the sun in July.

a. 147 million kilometers

b. 149.5 kilometers

c. 152 million kilometers

d. 154.5 million kilometers

The correct answer to this question is letter " a. 147 million kilometers."

Earth orbits the sun in an elliptical pattern. The equation of Earth's path is (x+2.5) ^2/22350.25 + y^2/22344=1 where the measurements represent millions of kilometers. The sun is located at the focus whose coordinate is (0,0). In January, Earth is located at one of the vertices, which is 147 million kilometers from the sun. The reason behind why January and July have the same distance is because July is the second half of a year. And it says, it is an ellipse form.
