Answer

12 seconds

Explanation

To find the time it takes for the stone to reach its highest point, we need to find the vertex of the parabolic function h(t) = -16t^2 + 40t, which represents the height of the stone above the ground. The vertex of a parabola in the form y = ax^2 + bx + c is given by the formula x = -b / (2a).In this case, a = -16 and b = 40. Plugging these values into the formula, we get:t = -40 / (2 * -16)t = -40 / -32t = 1.25The stone reaches its highest point after 1.25 seconds.
