On a windy morning, a hot air balloon starts rising and flying away from the top of a

hill. The altitude, h, in feet, of the balloon x hours after starting its ascent from the
hill, can be modeled by the function: h(x) = -16x2 + 64x + 80.
The balloon will reach its maximum height after how many hours?
