18.Consider the function that relates time and distance as sound travels through the air. An observer can estimate the distance to an approaching thunderstorm by counting the seconds between a flash of lightning and the resulting sound of thunder. Every 5 seconds, sound travels approximately 1 mile. If you count up to 10 seconds before hearing the thunder, the storm is approximately 2 miles away. In this example, distance is a function of time.
The concept of slope occurs in many applications of mathematics. For example, highway engineers measure the slope of a road by comparing the vertical rise to each 100 feet of horizontal distance. The Federal Highway Administration recommends a maximum vertical rise of 12 feet for every 100 feet of horizontal distance. Many secondary roads and streets are much steeper. Filbert Street in San Francisco has a vertical rise of approximately 1 foot for every 3 feet of horizontal distance. By comparison the walls at the ends of the Daytona International Speedway have a vertical rise of 3 feet for every 5 feet of horizontal distance.
Find and describe another example of how slope is used in one's every day life.
