Allison is pushing a 70 pound box up a ramp. How does the ramp help her move the box?

• It increases the distance the box must move but decreases the force needed.

• It decreases the distance the box must move but increases the force needed.

• It increases both the distance the box must move and the force needed.

• It decreases both the distance the box must move and the force needed.
