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?

  • Math -

    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.
