A 65kg boy is sitting on a seesaw 0.6 m from the balance point. How far from the balance point should a 40kg girl sit so that the seesaw remains balance?

The magnitude multiplied by the direction should be the same on both sides. So for the boy, it would be (65 kg x 0.6)= 39. Therefore the mass of the girl multiplied by the distance should equal 39 as well. So (39=X x 40). x = 0.975
