Well, isn't that a lovely question! Sound travels at about 343 meters per second in air. To find out how long it will take for sound to travel 40,000 kilometers, we need to convert that distance to meters and then divide it by the speed of sound. So, it will take approximately 32 hours for the sound to travel that distance. Just imagine all the beautiful landscapes and happy little trees the sound will pass along the way!
It takes 1.3 to 1.4 nanoseconds for light to travel 1 foot.

There is no sound in space.
The speed of sound in air is approximately 343 meters per second. To convert this to miles per hour, we multiply by 3600 seconds per hour and divide by 1609.34 meters per mile, giving us roughly 767 mph. Therefore, it would take approximately 1 minute and 34 seconds for sound to travel 20 miles in ideal conditions.

Since the moon has little to no atmosphere, sound cannot move as it has no medium to travel thru.
That depends on the speed at which one is traveling.
Sound waves can't travel through space.
Sound travels at approximately 343 meters per second in air at room temperature. Therefore, it would take about 2.9 seconds for sound to travel 1000 meters in air.
