Question 1118219
West of Albuquerque, New Mexico, Route 40 eastbound is straight and makes a steep descent towards the city, The highway has a 6% grade which means that its slope is -6/100. Driving on this road you notice from elevation signs that you have descended a distance of 100 ft. What is the change in our horizontal distance?
------------
Use a right triangle.
Vertical leg = 100 feet
tan(6) = 100/horizontal
horizontal distance = 100/tan(6) =~ 951.4 feet
