1. when people talk about how fast they drive, what are they actually referring to?

velocity
speed
acceleration
time
clear all

Explanation:

Speed refers to how fast an object is moving and is a scalar quantity. When people casually talk about how fast they drive, they usually mean the magnitude of their motion without considering direction (which is what velocity includes as a vector quantity). Acceleration is about the rate of change of velocity, and time is not what is meant by how fast one drives.
