Question

a walkway rises 6.5 ft for every 5 ft on the horizontal. find its slope (or grade). c. 65% d. $\frac{5}{6.5}$ e. 10 f. 13 g. 130% h. $\frac{6.5}{5}$

Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{\text{rise}}{\text{run}}$.

Step2: Identify rise and run

The rise is 6.5 ft and the run is 5 ft.

Step3: Calculate the slope

$m = \frac{6.5}{5}=1.3$. To convert to percentage for grade, we multiply by 100, so $1.3\times100 = 130\%$.

Answer:

G. 130%
