You can put this solution on YOUR website! Sue weighs 45 pounds, and her father weighs 170 pounds. If Sue sits on one end of a 20-foot-long seesaw with the fulcrum in the middle, how far from the fulcrum should her father sit to balance the seesaw?
----------
Sue is 10 ft from the middle.
---------
Sue's leverage is 45*10 = 400 ft-lbs
---------
Dad's leverage is 170x where "x" is his distance from the fulcrum.
-----
Equation:
170x = 400
x = 2.2857 ft from the fulcrum.
