You may have to convert from feet to miles several times in this assignment. You can use 1 mile = 5,280 feet for your conversions.

1. Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: , where C is a constant, and r is the distance that the object is from the center of the earth.

a. Solve the equation for r.

What is the equation?

To solve the equation W = C/r for r, we need to isolate the variable r.

Step 1: Start with the equation W = C/r.

Step 2: Multiply both sides of the equation by r to get rid of the fraction:

W * r = C.

Step 3: Divide both sides of the equation by W to isolate r:

r = C/W.

Now you have solved the equation W = C/r for r.
