Beniamin, who weighs one hundred five pounds, sat eight feet from the center of a seesaw. Dylan sat three feet on the other side of the center to balance the seesaw. How much does Dylan weigh?

Answer 1

To balance the seesaw, the two weights and their distances from the center must be equal:

105 pounds x 8 feet = Dylan's weight x 3 feet

840 = 3D

Dylan weighs 280 pounds.
