The speed of sound in Colorado is about 750 mph, which is about 1100 ft/s. At Coors Field in Denver, it is about 500 feet from home plate to the back row behind center field. If you were sitting in these seats, how long would the delay be between you seeing the batter hit the ball and hearing the crack of the bat? You may neglect the small amount of time it takes for the light to travel the 500 ft.
