Sound travels at about 330m/s in normal air. First put 40km into metres which is 40,000m. We can then rearrange the distance=speed x time equation to time=distance/speed. After this we can just substitute in the values so that time=40,000/330=121.21212 Therefore it would take 121.21 seconds (about two minutes) for sound to travel 40km.

On January 19, 2006 a space probe was launched and sent to Pluto. It was expected to reach Pluto in 2015. So it would take about 9 years to get to Pluto.
You would have to move at least 73000km/hr, or about 45300mph to reach Pluto in 9 years.

Sound waves are the sound. The waves cause vibrations in the objects that they collide with, and then the vibrated objects create more waves with their vibrations. An example of this would be listening to someone on the other side of a door.
At a speed of 3 trillion miles per hour, Earth would reach Pluto in about 30 minutes, as the distance between Earth and Pluto is approximately 3.67 billion miles on average.
Collecting sound involves gathering audio signals using a microphone or other recording device. Capturing sound waves refers to the process of converting these sound waves into electrical signals that can be stored or processed digitally. In essence, collecting sound involves capturing sound waves as part of the overall process.
Sound waves travel the fastest through nonporous solids.
it would take about 23 years
