Info about "Speed of sound"

Definition: If an object travels at the speed of sound in air at 20 degrees Celsius for one second, it travels a distance of 343 meters per second. Actually, it is equivalent to 1.234,8 km/h.

The speed of sound is often illustrated by an example of a thunderstorm: if lightning strikes within 3 seconds of the thunder sound, then the thunderstorm is about 1 kilometer away. Another example, in a 100-meter sprint, the starting shot is fired directly next to the starting blocks. Imagine, if the start shot was fired at the finish line, it would take about 0.3 seconds of time to hear the shot in the start blocks.

Info about "Kilometers per hour"

Kilometers per hour is used as a standard unit in transportation, therefore it is used in traffic or to measure the travel speed of vehicles. For example, a commercial aircraft flies at a speed of 1,000 km/h then it covers a distance of 1,000 kilometers per hour.

The unit is defined as follows: An object moving at 1 "km/h" per hour will cover one kilometer. "km/h" is approved to use in the international system of units (SI).
