Answer:

The answer is B - 4.

Step-by-step explanation:

This is because you have to divide the length of the slope by its height to find the mechanical advantage of a incliuned sliope

The correct answer is
B. 4

In fact, the mechanical advantage (MA) of an inclined plane is equal to the ratio between the length of the plane and its height:

MA= (L)/(h)

The ramp in this problem has a length of L=120 in and a height of h=30 in, therefore its mechanical advantage is

MA= (L)/(h)= (120 in)/(30 in)=4
