Question 1082537: A satellite orbits aroudn the earth in an ellipse orbit of eccentricty 0.80 and with semi-major axis of length 20,000 km. If the center of the earth is at one focus, find the maximum altitude (apogee) of the satellite.

.
the maximum altitude (apogee) = the length of the major semi-axis PLUS the half of the focus distance = 

20000 + 0.8*20000 = 20000 + 16000 = 36000 kilometers.

Answer. 36000 km.
