Info about "Speed of light"

Definition: If an object moves at the light speed for one second, it travels a distance of 299,792.458 km or about 300,000 km. This is the light speed that light travels in a vacuum.

This speed is also used to propagate radio signals, which is very important in space travel. For example, a signal from Mars takes about 3 to 20 minutes to reach Earth depending on its actual position. We notice a sunrise on earth about 8 minutes later because the light of the sun arrives to our eyes at that time.

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).
