Considering that you are a civil engineer responsible for designing a parabolic bridge that crosses a river, you need to determine the maximum height that the bridge can reach. When performing preliminary calculations, you discover that the bridge follows the equation of the parabola y = -2x² + 10x - 6, where y is the height (in meters) and x is the distance (in meters) from the starting point of the bridge. What is the distance at which the bridge reaches its maximum height?
