Let W = the weight of the person.
Let d = the distance of the person from the center of the earth.
Because the radius of the earth is 3900 miles, d = 3900 miles.
The weight of the person varies inversely as the square of the distance the person is from the center of the earth.
Therefore
where k = constant.
When d = 3900 miles, W = 192 pounds.
Therefore
Multply each side by 3900².
k = 2.9203 x 10⁹.
