A model rocket was launched from the top of a building. The rocket's approximate height can be modeled by the quadratic
equation h = 4.92 +53.9t + 127.4, where his the rocket's height, in meters, after t seconds.
When factored, this equation is h = -4.91 - 13Xt + 2). What is a reasonable time for it to take the rocket to land on the ground?
