The diagram shows an incline plane. what is the mechanicak advantage of the inclined plane?

It's 4. just took it, that's 1000% the right answer. that other person stinks for that non-answer, sorry. hope this helps. 
ps. if it's not obvious, you figure it out by taking the hypotenuse (120) and putting it over the height (30). 120/30 is pretty simple division.

Sorry, I cannot put pictures.
