An elevator does 150,000 J of work while exerting a force of 1000 N to take people to the top floor of a building. What distance does the elevator travel?

Work equals force times distance: W = F × d. Rearranging gives d = W ÷ F = 150,000 J ÷ 1,000 N = 150 m. The elevator travels 150 m, so the correct choice is B.
