Question

Two people are sitting on a seesaw that is 9 ft long. How far from the 120-pound person should the fulcrum be placed so that the seesaw balances?

A. 3 ft
B. 4.5 ft
C. 6 ft
D. 9 ft

Answer 1

To balance a seesaw with two people of different weights, the heavier person should sit closer to the fulcrum, while the lighter person should sit farther from the fulcrum.

Step-by-step explanation:

To balance a seesaw, the heavier person should sit closer to the fulcrum, while the lighter person should sit farther from the fulcrum. In this case, we have a 120-pound person and another person, whose weight is not mentioned. Since we need to balance the seesaw, the distance from the fulcrum should be inversely proportional to the weights. The weight of the other person is not specified, so we cannot determine the exact distance. Therefore, we cannot determine the correct answer from the provided options.
