The Batmobile, starting from rest, speeds up with an acceleration of magnitude 2.25 m/s2 through a distance of 225 m. It then applies the brake and slows down with an acceleration of magnitude 0.750 m/s2, until it finally stops after having traveled an additional distance of 675 m. Calculate the time that it takes to travel the entire 900 m from start to finish.
