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

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

Explanation:

we know that

The formula to calculate the slope is equal to

`m=(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=(2.5)/(10)=0.25`

convert to percentage

`0.25*100=25\%`
