Dimas reads that it takes 270 N to lift a firefighter’s equipment. If a firefighter does 5400 J of work carrying the equipment up a staircase, how high does the firefighter climb? (Work: W = Fd)

Use the work formula W = Fd and solve for distance: d = W ÷ F. Substituting the values gives d = 5400 J ÷ 270 N = 20 m. The firefighter climbs 20 m, which is choice A.
