For a seesaw that 14 ft long, where should the fulcrum be placed to balance a 204 lbs adult and a 81.6 lbs child?
For a seesaw to balance, weight X distance on one side of the seesaw has to equal weight X distance on the other side.
x = distance of adult
14 - x = distance of child
204x = 81.6(14 - x)
Simplify the equation and solve for x.
