ATV+and+Ramp+hint

The ramp, or inclined plane, that Chris has chosen to use is a typical simple machine that allows him to harness mechanical advantage. We learned that W = F x D can be used to calculate mechanical advantage. Therefore, getting the ATV into the truck is the W, or WORK, the 2 meter long plank is the D, or DISTANCE, and the difficulty in pushing the ATV up the ramp is F, or FORCE, then what does Chris have to change to decrease the FORCE needed to do the same WORK?

Remember, different combinations of F and D can be used to get the same W.
