Speed = distance / ?

**The reasoning** Speed tells us **how fast something moves**. To find speed, you need to know: - How far it traveled (distance) - How long it took to get there (time) The formula is: **Speed = Distance ÷ Time** Think about it: If you travel 100 km in 2 hours, your speed is 100 ÷ 2 = 50 km/h. You're dividing the distance covered by the time it took. This is a **fundamental definition** in Physics — speed is the rate of covering distance. **Why the wrong options tempt you** - **Force (A)** sounds physics-y, but force is about *push or pull* (F = ma), not how fast you move. - **Mass (C)** might confuse you because heavier objects *feel* slower, but mass doesn't define speed. - **Power (D)** relates to energy and work done per time, not distance covered per time. These options throw physics terms at you hoping you'll panic and guess. Don't fall for it! **Quick takeaway** Speed is always "distance per unit of time" — no distance, no time, no speed calculation!
