Addison and Noah are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Addison is 308 miles away from the stadium and Noah is 248 miles away from the stadium. Addison is driving along the highway at a speed of 64 miles per hour and Noah is driving at speed of 44 miles per hour. Let A represent Addison's distance, in miles, away from the stadium t hours after noon. Let N represent Noah's distance, in miles, away from the stadium t hours after noon. Write an equation for each situation, in terms of t, and determine whether Addison or Noah is closer to the stadium 4 hours after noon.
