a plane that carries mail makes a round trip each day from chicago to new york. it makes 1 intermediate stop on the way to new york nad 1 intermediate stop on the way back to chicago suppose you make a graph of the altitude of the plane for one day with time on the horizontal axis and altitude on the vertical axis how many times will the graph touch the horizontol axis

The plane makes 2 intermediate stops on its way to New York and 2 intermediate stops on its way back to Chicago. Therefore, the graph of the altitude of the plane will touch the horizontal axis a total of 4 times in one day.
