Question

The roof of a barn rises vertically 2.5 meters through the horizontal distance of 10 meters. What is the pitch (slope) of the roof?

Answer 1

Answer:

The pitch (slope) of the roof is $0.25$   or $25\%$

Step-by-step explanation:

we know that

The formula to calculate the slope  is equal to

$m=\frac{y2-y1}{x2-x1}$

where

${y2-y1}=2.5\ m$  -----> is the vertical distance (rise)

${x2-x1}=10\ m$  -----> is the horizontal distance (run)

therefore

$m=\frac{2.5}{10}=0.25$

convert to percentage

$0.25*100=25\%$
