A lever pivots on a support called a fulcrum. (as shown in the picture)
For a balanced lever, the distance d (in feet) an object is from the fulcrum varies inversely with the object's weight w (in pounds). An object weighing 120 pounds is placed 10 feet from a fulcrum. How far from the fulcrum must a 108 pound object be place to balance the lever?
(round your answer to the nearest tenths place, enter the number only (no units))
