### Calculating the K-Design Value for a Roadway **Problem Statement:** What is the K-design value for a roadway designed for 70 mph, given: - G₁ = -2.5% - G₂ = 3.9% **Explanation:** K-value is a design parameter used in vertical alignment design of roadways. It represents the horizontal distance (in feet) required for a 1% change in gradient. The K-value can be calculated using specific formulas and standards provided by engineering guidelines. The provided problem requires the calculation of the K-value given the design speed and gradients. ```plaintext __________________________________ | | | Enter your answer here | |__________________________________| ```
