The Speed that we know.
Speed is how fast something is going. Another way to think of this is as how far you can go in a certain amount of time.(taken fromhttp://van.physics.illinois.edu/qa/listing.php?id=142)
Speed is used in daily life to help us see how fast we are going, it also helps us to measure the distance and time, hence speed is very useful and is needed greatly in daily life.
