Which term is used to express speed in relation to distance and time?

The term used to express speed in relation to distance and time is velocity. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. It describes how fast an object moves and in what direction, allowing for a comprehensive understanding of the object's motion. In contrast, other terms such as vascularity pertain to blood vessel health and circulation, veracity relates to truthfulness or accuracy, and vitality refers to the state of being strong and active, none of which convey the concept of speed in the context of distance and time.
