1. The problem is to understand the concept of speed. 2. Speed is defined as the distance traveled divided by the time taken to travel that distance. 3. The formula for speed is $$\text{speed} = \frac{\text{distance}}{\text{time}}$$. 4. Important rules: - Distance must be in consistent units (e.g., meters, kilometers). - Time must be in consistent units (e.g., seconds, hours). 5. To calculate speed, measure the total distance traveled and the total time taken. 6. Divide the distance by the time to get the speed. 7. For example, if a car travels 100 kilometers in 2 hours, the speed is $$\frac{100}{2} = 50$$ kilometers per hour. 8. Speed tells us how fast an object is moving regardless of direction.
