Hearing thunder after seeing lightning is an example of sound taking time to travel, as light travels much faster than sound. Echoes in a large canyon demonstrate that sound takes time to travel, as there is a delay between the original sound and the echo bouncing back.
The speed of sound is measured by timing how long it takes for a sound wave to travel a known distance. By dividing the distance by the time taken, the speed of sound can be calculated.
To travel where? - That would depend on the distance you want it to travel. In air, sound moves at about 310 meters per second (depends on the temperature). This is about 1,236 kilometers per hour (or 768 mph).
Sound travels at a speed of about 343 meters per second, or 1,236 kilometers per hour. It takes sound roughly 3 seconds to travel 1 kilometer.
Based on the speed of sound being 340 m/s and that of light being 299,792,458 m/s. we get the speed of light being ~881,742 times that of sound. So if sound goes 1cm then light will travel 881,742 cm or 8,817.42 m.

Fire crackers or thunder and lighting.
Gases have the least amount of molecules and they are spread farther apart so it takes a longer time for the sound energy to travel from molecule to molecule.

It takes 3 seconds.
The FIRST sound would be the crack of the bullet making a sonic boom- most travel faster than the spped of sound. The second is the sound of the gun firing- it takes longer for the sound to get to you than the bullet takes to get to you.

In dry air at sea level and atmospheric pressure, 1.69 seconds.
A steel specimen would give a longer or continuous sound when beaten by a hammer. This is due to the malleable nature of the material. In other words, sound takes longer to travel in a coarse-grained material. Whereas cast iron specimen gives sound of shorter duration. This is due to the brittle nature of the material. In other words, sound takes shorter to travel in a fine-grained material.
The time it takes for the sound to travel to the cliff and back as an echo is 4 seconds. Since the sound wave travels twice the distance to the cliff and back, the total distance traveled is 2 × 680 = 1360 meters. Using the formula speed = distance/time, we can calculate the speed of sound. The period of the sound wave is the time it takes for one complete cycle, which in this case is the time it takes for the sound to travel to the cliff and back, which we found to be 4 seconds.
