How much time would it take for the sound of thunder to travel 2000 meters if sound travels a speed of 330 meters per sec.
4 m/s
4m/5s = 0.8 m/s
I think it must be 8 times as much. That is 2752 meters in 8 seconds.
Light travels considerably faster.Sound travels at about 343 meters per second. Light travels at 299,792,458 meters per second.Light in vacuum travels about 876 thousand timesas fast as sound in air.If you meant to ask if light or sound travels faster then this is the answer:Light travels faster, with a speed of 300,000,000 m/s (which is equal to 300,000 km/s, or 186,282 miles per second). Sound, on the other hand, travels at a speed of 340 m/s (which is equal to 1126 ft/s).
So, the sound travels at about 340 meters per second. The answer is 340 meters X 5 seconds equals 1700 meters away is the lightning strikes.
1500 meters/330 meters per second = 4.55 seconds
what is the speed of a rocket that travels 9000 meters in 12.12 seconds
Thunder is the sound that lightening makes. Sound travels through air at "the speed of sound." Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second. As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.

Since sound travels at about 1100 feet per second at approximately 70 degrees Fahrenheit, you would be 5500 feet from the lightning. But you would be closer to the storm because lightning rarely occurs on the edge of a storm.
A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
4 meters/2 seconds = 2 meters/second.
Because the speed of light is faster than the speed of sound. In fact, light arrives at the observer virtually instantaneously, but sound takes almost 5 seconds to travel each mile. It's simple to observe lightening then count seconds until the thunder is heard to estimate the distance.

# Watch the sky for a flash of lightning. # Count the number of seconds until you hear thunder. If you have a watch with a second hand or a digital watch that has seconds, begin timing as soon as you see the lightning and stop as soon as you hear the thunder start. If you don't have a watch, do your best to count the seconds accurately. Say "One one thousand, two one thousand etc." in your mind for each second. # Divide the number of seconds by 5 to calculate the distance in miles (or divide by 3 for kilometers). In other words if you counted 18 seconds from when you saw the lightning, the strike was 3.6 miles (6 kilometers) from your location. The delay between when you see lightning and when you hear thunder occurs because sound travels much, much more slowly than light. Sound travels through air at about 1100-1200 feet (330-350 meters) per second (depending on altitude, relative humidity, pressure, etc.), which is a little more than one mile per five seconds (one kilometer per three seconds). In comparison, the speed of light is 983,571,058 feet (299,792,458 meters) per second.#* For example, if lightning strikes a point 1 mile away, you will see the strike approximately .00000536 seconds after the strike while you will hear it approximately 4.72 seconds after the actual strike. If you calculate the difference between these two experiences, a person will hear a strike approximately 4.71999 seconds after the strike actually occurred. Therefore, 5 seconds per mile is a fairly robust approximation.
40 meters/10 seconds = 4 meters per second.
