The height of a paper airplane thrown off a building that is 80 feet tall can be modeled by the function h(t) = - 16t ^ 2 + 64t + 80 where h represents the height in feet above the ground and t represents the time in seconds since the airplane was thrown. How long does the plane take to reach its peak height and what height did it reach?
