Question

subtract the elevation of point a from point b, what is the change in elevation? 400 question 8 1 pts if the horizontal distance between point a and point b is 2.8 km, what is the gradient? gradient = \frac{rise(m)}{run(km)}

Explanation:

Step1: Identify rise and run values

The change in elevation (rise) is given as 400 m from the previous part, and the horizontal distance (run) is 2.8 km.

Step2: Apply gradient formula

The gradient formula is $\text{Gradient}=\frac{\text{Rise}(m)}{\text{Run}(km)}$. Substitute rise = 400 m and run = 2.8 km into the formula: $\text{Gradient}=\frac{400}{2.8}\approx142.86$.

Answer:

$\approx142.86$
