Horizontal distance

The road has a gradient of 8%. How many meters will the road rise on a horizontal distance of 400m?

Correct answer:

x =  32 m

Step-by-step explanation:

$$\begin{gathered} v=400\text{ m } \\ x={\displaystyle \frac{8}{100}}\cdot v={\displaystyle \frac{8}{100}}\cdot 400=32\text{ m} \end{gathered}$$
