What is Speed?

$\boxed{\fcolorbox{white}{pink}{Answer:}}$

Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.
