SUMMARY

The horizontal run for a hill with a vertical rise of 800 feet and a grade of 8% is calculated using the formula 8% = rise/run. By rearranging the equation to solve for run, we find that run = rise / (grade/100). Substituting the values, run = 800 / (8/100), which results in a horizontal run of 10,000 feet. This calculation is essential for understanding slope and grade in civil engineering and construction projects.

PREREQUISITES
  • Understanding of basic algebra and equations
  • Familiarity with slope and grade concepts
  • Knowledge of vertical and horizontal measurements
  • Basic skills in unit conversion and percentage calculations
NEXT STEPS
  • Research the principles of slope calculation in civil engineering
  • Learn about different methods for measuring hill grades
  • Explore tools for calculating earthwork quantities in construction
  • Study the impact of slope on drainage and erosion control
USEFUL FOR

Civil engineers, construction project managers, students studying geometry or civil engineering, and anyone involved in land surveying or grading projects.

The grade of a hill is a slope and is stated as a percent. What would the horizontal run be for a hill with a vertical rise of 800 feet and a grade of 8%? :confused:

You might want to try posting questions like this in the Homework Help Forum. Anyway:

[tex]8\% = \frac 8 {100} = \frac{\rm rise}{\rm run} = \frac{800}{\rm run}[/tex]

Solve for the run.
 
Thank you.
