A certain highway has a 7% grade. how many feet does it rise in a horizontal distance of 1 mile? (1 mile = 5280 feet. round your answer to one decimal place.)

For this case we have the following relationship:

(x / 5280) = (7/100)

From this relationship we must clear the value of x.

Clearing we have:

x = (7/100) * (5280)

Calculating we have:

x = 0.07 * 5280

x = 369.6 feet

Answer:

it does rise in a horizontal distance of 1 mile а bout:

x = 369.6 feet
