Movers needed to move a heavy box from the bottom of some stairs to the top of the stairs. They placed a ramp over the stairs and pushed the box up the ramp. Which best explains why the movers used a ramp to move the box?

• The ramp reduced the amount of

  force needed to move the box.

• The ramp increased the height that

  the box needed to be moved.

• The ramp reduced the distance that

  the box needed to be moved.

• The ramp increased the amount of
