5 miles = (5) (5280 feet) = (5) (5280) (12 inches) = 316,800 inches. 316,800 inches / 250,000 = 1.27 inches) Look at any map of the United States and notice the kinds of place names (toponyms) that appear. For example on a map of Texas you will see cities or towns named San Angelo and San Antonio, Houston and Austin, New Braunfels and Fredericksburg, Amarillo, Midland, and El Paso, among many. Place names can give clues to past cultural landscapes. They can also offer evidence of past migrations (sequent occupance) in an area, even when time has erased other evidence. In this example, the elevation at the spot marked A is about 4400 feet above sea level as indicated on the contour line close to it. Point B is not close to a line number. By paying attention to the light and dark lines, you can figure out that it is about 4350 feet. Source.
