# Speed and Distance

The distance is a physical concept that describes how far or how near is an object from a point. It also represents length of space between two points. This is a scalar quantity.

The speed is said to be a measure of distance per unit time, i.e. it is the distance covered in a unit time interval.

Speed and distance are two quantities that are directly proportional to each other. The third quantity introduced to make them equivalent is the time factor. Whenever we talk about speed and distance, the time factor can never be ignored.
