A stone is dropped into a water well, the sound when the stone hits the water is heard 16 seconds later, as shown in the figure below. Estimate the distance from the edge of the well to the surface of the water, taking into account the time it takes for sound to rise from the bottom of the well to the surface. The speed of sound in air is 343 m / s @ 20 ° C.

Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed ?min to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between ?min and the speed of light ?. ?−?min= m/s
