The mechanical advantage of an inclined plane can be calculated using the formula:

[tex]IMA= \frac{length of the slope}{height of the ramp} [/tex]

The length of the ramp: 20ft
The height of the ramp: 5ft

[tex]IMA= \frac{length of the slope}{height of the ramp} [/tex]
[tex]IMA= \frac{20ft}{5ft} [/tex]
[tex]IMA= 4 [/tex]

The answer is then C.
