Given :
Two children are playing on a seesaw. The child on the left weighs 50 lbs. And the child on the right weighs 100 lbs.
To Find :
If the child on the left is 3 feet from the pivot, how far must the child on the right be from the pivot from the seesaw to be balanced.
Solution :
We know, for seesaw to balance :

Here,
is distance from origin from pivot point.
Putting all the values in the equation, we get :

Therefore, distance of right child from pivot to balance the seesaw is 1.5 feet.
Hence, this is the required solution.
