Suppose that xx is a distance from the fulcrum to the second child. The equation of equilibrium has the form: 405=x5040\cdot5=x\cdot50. We receive: x=20050=4x=\frac{200}{50}=4. Thus, the second child is 4ft4\,\textrm{ft} from the fulcrum.

Answer: the second child is 4ft4\,\textrm{ft} from the fulcrum.
