For a science experiment, a projectile is launched. Its path is given by h(d) = -4.0d² +61.3d + 20.9, where h is the height of the projectile above the ground and dis the horizontal distance of the projectile from the launch pad, both in metres. How far away from the launch pad is the projectile when it begins to fall, to the nearest tenth of a metre?
