Question 1104872: Inverse Variation:
If a body is above the surface of the Earth , its weight varies inversely as the square of the distance of the body from the center of the Earth. If a man weighs 160 lb on the surface of the Earth, how much will he weigh 200 mi above the surface? Assume the radius of the Earth is 4000 mi.
Thanks in advance. :)

W=k/r^2
160=k/4000*4000
k=2.56*10^9use k in second part
w=2.56^10^9/(4200^2)
=145.12 lb.
