Answer:

1.33 m

Explanation:

Tom weighs 600 N and is 2 meters from the pivot.  So his moment is:

τ = Fr

τ = (600 N) (2 m)

τ = 1200 Nm

To balance the see-saw, Jeremy must create an equal and opposite moment.

τ = Fr

1200 Nm = (900 N) r

r = 1.33 m

So Jeremy must sit 1.33 m from the pivot on the other side.
