At what altitude above the Earth's surface would your weight be three-fifths of what it is at the Earth's surface? Assume re = 6.371 10^3 km.

If weight decreases as the inverse square of distance, then

3/5= (re/r)^2

where r is the distance from the center of earth to the spot you are interested.

altitude = r - re
