12) Amusement Parks A thrill ride at an amusement park carries riders 160 feet straight up and then releases them for a free fall. The time t in seconds that it takes an object in free fall to reach the ground is t = $\sqrt{ \frac{d}{16} }$
where d is the distance in feet that it falls. How long does it take the riders to reach the ground? Give your answer as a radical expression in simplest form. Then estimate the answer to the nearest tenth of a second.
