Question 1208015
.
The weight of a body above the surface of Earth varies inversely with the square of the distance from the center of Earth. 
If a certain body weighs 55 pounds when it is 3960 miles from the center of Earth, how much will it weigh 
when it is 3965 miles from the center?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



If to apply the common sense,  then the solution is in one line:


        the body's weight at the distance of 3965 miles from the center of the Earth is 


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{{{55*(3960/3965)^2}}} = 54.86137 pounds &nbsp;&nbsp;&nbsp;&nbsp;(rounded).  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>



I solve the problem in this way in order for you do not miss this 
rare and fortunate opportunity to develop your common sense.
