Question 519936: In 1927, Charles Lindbergh made history by making the first transatlantic flight from New York to Paris. It took Lindbergh approximately 33.5 hours to make the trip. In 1997, the Concorde could make the trip in approximately 3.3 hours. Write a linear equation of the time, in hours, it takes to cross the Atlantic in terms of the year. Use your equation to predict how long a flight between the two cities would have taken in 1967. Round your answer to the nearest tenths. On the basis of your answer do you think a linear model accurately predicts how the flying time between New York and Paris has changed?
