Question

A 75 lb boy and a 65 lb girl play on a seesaw. The seesaw is 14 ft long and is pivoted exactly in the middle. If the girl sits on the end of her side, where must the boy sit to make the seesaw balance?

Answer 1

Answer: 6 feet from the pivot point

Explanation:

Girl's weight x distance from center = Boy's weight x distance from center

65 (7) = 75x

`(65(7))/(75)=x`

6.066 = x

The boy needs to be placed 6 feet from the center (aka pivot point) which is the same as saying 1 foot from the end of the seesaw.
