A baseball is thrown with a vertical velocity of 40 ft/s from an initial height of 7ft. The height h in feet of the baseball can be modeled by h(t)=-16t^2+40t+7, where t is the time in seconds since the ball was thrown.

Approximately how many seconds does it take the ball to reach maximum height? Round your answer to the nearest tenth.
