Final answer:
The maximum distance between the satellite and the Earth is 6620 km.
Step-by-step explanation:
To find the maximum distance between the satellite and the Earth, we need to determine the semi-major axis of the elliptical orbit. In this case, the semi-major axis is represented by the square root of the denominator in the equation that models the orbit: x^2/43,824,400 + y^2/47,196,900 = 1. The semi-major axis is equal to the square root of 43,824,400, which is approximately 6620 km.
Therefore, the maximum distance between the satellite and the Earth is 6620 km.
