Two piles of heavy boxes must be lifted onto a shelf. Each pile has 20 boxes and each box is the same size and weight. Tom and Claudia are each responsible for a pile. Tom lifts each box straight up from the pile to the shelf. Claudia places a long, gradual ramp that leads from the pile to the shelf. She pushes each box up the ramp until it rests on the shelf.

Compare the distance each person moved each box. Who moved the boxes a longer distance?
