Answer: OPTION B.
Explanation:
By definition, the slope equals the Rise divided by the Run; then, the slope can be found using the following formula:
Where "Rise" is the vertical change between two points and "Run" is the horizontal change between those two points.
In this case you can identify in the figure that:
Knowing these values, you can substitute them into the formula.
Through this procedure you get that the slope of the ramp is:
