1. The problem is to find the speed of a car. 2. Speed is defined as the distance traveled divided by the time taken. 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 or kilometers). - Time must be in consistent units (e.g., seconds or hours). 5. To find the speed, measure the distance the car travels and the time it takes. 6. Substitute these values into the formula and calculate. 7. For example, if a car travels 100 kilometers in 2 hours, speed is $$\frac{100}{2} = 50$$ kilometers per hour. 8. This means the car's speed is 50 units of distance per unit of time.
