Comprehensive Overview

Definitions

Distance: This is the total length of the path traveled by an object. It is a scalar quantity, meaning it only has magnitude (size) and no direction. Common units of distance include meters (m), kilometers (km), miles (mi), and feet (ft).
Speed: This refers to how quickly an object is moving. It is defined as the distance traveled per unit of time. Like distance, speed is a scalar quantity. Common units of speed include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).
Time: This is the duration of an event or the interval between two points in time. It is a fundamental quantity in physics and is measured in units such as seconds (s), minutes (min), hours (h), and years (yr).

The Fundamental Formula

The relationship between distance, speed, and time can be expressed by the following formula:

Distance = Speed × Time

This formula is the foundation for solving problems involving these three quantities. By rearranging the formula, we can also find speed and time:

Speed = Distance / Time
Time = Distance / Speed

These formulas make it possible to calculate any one of the three variables if we know the other two.

Scientific Foundations

The study of distance, speed, and time is rooted in classical mechanics, particularly kinematics, which deals with the motion of objects without considering the forces that cause the motion. The concept of speed is derived from the more fundamental idea of velocity, which is a vector quantity that includes both magnitude (speed) and direction Turns out it matters..

In physics, uniform motion refers to an object moving at a constant speed in a straight line. In this case, the formulas above provide an accurate description of the motion. That said, in real-world scenarios, motion is often non-uniform, meaning the speed and/or direction of the object changes over time. To analyze non-uniform motion, more advanced concepts like acceleration and calculus are required Small thing, real impact..

This is where a lot of people lose the thread.

Historical Context
