Sofia and Josiah are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Sofia is 500 miles away from the stadium and Josiah is 375 miles away from the stadium. Sofia is driving along the highway at a speed of 50 miles per hour and Josiah is driving at speed of 25 miles per hour. Let SS represent Sofia's distance, in miles, away from the stadium tt hours after noon. Let JJ represent Josiah's distance, in miles, away from the stadium tt hours after noon. Graph each function and determine the number hours after noon, t,t, when Sofia and Josiah are the same distance from the stadium.
