Question 1100444: The planet Saturn moves in an elliptical orbit with the sun at one focus. Given that Saturn's closest approach to the sun is approximately 1352.55 million kilometers and that the eccentricity of Saturn's orbit is approximately 0.056, estimate this planet's maximum distance from the sun. Express your answer as a decimal rounded to two decimal places.
Please help, I don't even know where to begin.

You can use the definition of eccentricity,
e=+%28r%5Bmax%5D-r%5Bmin%5D%29+%2F%28r%5Bmax%5D%2Br%5Bmin%5D%29
r%5Bmax%5D-1352.55=0.056%28r%5Bmax%5D%2B1352.55%29%29
r%5Bmax%5D-1352.55=0.056r%5Bmax%5D%2B75.7428%29%29
0.944r%5Bmax%5D=1428.2928%29%29
Solve for r%5Bmax%5D.
