distance traveled over time passed
Explanation:
Speed is a measure of the distance that an object travels over the time passed to travel such distance.
The speed of an object is defined as follows:
![speed=\frac{distance}{time} \\s=\frac{d}{t}](/tpl/images/0640/8973/8b01d.png)
where
is the distance and
is the time
thus speed is the division of the total distance that is traveled in a certain time.
