## 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 "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.
