Question

the slope of a ramp from the sidewalk to the street has to be 1/20. the height of a ramp is 2.5 inches.what is the horizontal length of the ramp

Answer 1

`\bf slope = {{ m}}= \cfrac{rise}{run}\implies \cfrac{1}{20} \\\\\\ \cfrac{\stackrel{height}{2.5}}{\stackrel{length}{x}}=\cfrac{\stackrel{rise}{1}}{\stackrel{run}{20}}\implies \cfrac{2.5\cdot 20}{1}=x`
