Question

Some roads in the Rocky Mountains have a rise of 7 feet for every 100 horizontal feet.What is the slope of such roads?

Answer 1

Let's begin by listing out the information given to us:

The road rises by 7 feet every 100 horizontal feet

The equation becomes:

Slope (m) = Δy/Δx = 7/100 = 0.07

Slope (m) = 0.07
