Speed is the rate of motion, or equivalently the rate of change in position, often expressed as distance d traveled per unit of time t.
Speed is a scalar quantity with dimensions distance/time; the equivalent vector quantity to speed is known as velocity. Speed is measured in the same physical units of measurement as velocity, but does not contain the element of direction that velocity has. Speed is thus the magnitude component of velocity.
In mathematical notation, it is simply: v = d / t
where v:speed, d:distance, and t:time.

How Others Use Our Site
I am hoping I will learn how to do word problems related to Solving Systems of Linear Equations in Two Variables. It is an area I am having the most trouble.. especially related to distance (2 autos traveling at different speeds, etc.) problems where speed is unknown.
A picture is worth a thousand words, and watching the videos is like reading chapters of the textbook in ligthening speed with great understanding of the material.
If I didn`t have dial-up and could have fast enough speed to watch and listen to the videos.. I think this would be one of the three best sites yet to help out with my tutoring for the pre-teens and teens here.
God bless and thank you so much.
To better understand math and to go at my own speed with the crowd of a class full of people.
Improve speed overall.
