A football is punted from a height of 3.5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function (t)=-16t²+45t+3.5, where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5.5ft on the ball’s descent, how long was the football in the air? Round to the nearest hundredth.
