## What is Speed?

Speed is the measure of how quickly an object moves or the rate at which it covers a distance. It is calculated by dividing the distance traveled by the time taken to cover that distance:

speed = distance / time.(alert-success)

Commonly, speed over land is measured in miles per hour (mph) or kilometers per hour (km/h), while speed over sea is measured in knots. The speed of sound is approximately equal to 767.27 miles per hour or 1,235 kilometers per hour.
