The entrance to an accessibility ramp is at ground level. The first section of the ramp covers a horizontal distance of 18 feet and rises to a landing 1.5 feet above the ground.

The second section of the ramp begins at the landing. It rises at a slope of 1/18
and covers another 9 feet of horizontal distance to reach the door.

NOTE: Sketch not drawn to scale.

Answer the questions to compare the sections of the ramp.

1. What is the slope of the ramp from the ground to the landing? Write your answer as a fraction with a whole-number numerator and denominator.

Write your answer in the space below.

2. Is the steeper part of the ramp from the ground to the landing or the landing to the door? Explain how you decided which part of the ramp is a steeper.

Write your answer in the space below.

3. Slope is equal to rise divided by run. If you know the horizontal distance (run) and the slope, how can you find the vertical distance (rise)?

Write your answer in the space below.

4. What is the vertical distance (rise) from the landing to the door? Show your work.

Write your answer in the space below.

5. What is the total height of the door above the ground?

Write your answer in the space below.
