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 "Miles per hour"

The unit of length known as a "mile" and it should not be confused with the nautical mile and very commonly used in the Anglo-American countries. Therefore, the metric system is defined in miles (instead of kilometers) per time unit. For example, if a vehicle travels at a speed of 100 miles per hour (100 mph), it will move around 160 km per hour in the metric system.

The units are defined as follows: An object moving at 1 "mph" per hour will cover a distance of one mile. Therefore, 1 mile is equivalent to 1.609344 kilometers.
