Inez throws a ball upward from her apartment balcony and the ball falls to the ground below. The height of the ball above the ground in feet is modeled by the quadratic function h(t) = -16t^2 + 32t +48, where t is the time in seconds that the ball is in the air. What is the total time that the ball was in the air?
