Preliminary Basic Calculations: The speed of sound is fast, but clearly not as great as the speed of light. There is a common observation that you can tell how far away a bolt of lighting is by counting the time in seconds between the flash (which arrives almost instantaneously) and the thunder. Each second of delay means the strike is 1/5 of a mile away. This implies that sound travels about 1/5 mile/sec or (5280/5) ft/sec≈ 1000 ft/sec. TH THE 911 (A) What is the approximate speed of sound in meters/sec?
