Speed is fundamentally about how much distance you cover per unit time—it's the rate of change of position. The key insight is that these three quantities are linked by a simple proportional relationship: if you know any two of them, you can always find the third by rearranging. Think of it as a triangle where distance sits at the top and speed times time sits at the bottom, making it easy to see which operation (multiply or divide) gets you what you need.
