To calculate speed, you can use the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
Here’s how it works:
1. **Distance**: Measure how far an object has traveled, usually in units like meters, kilometers, miles, etc.
2. **Time**: Measure how long it took to travel that distance, typically in seconds, minutes, or hours.
### Example:
If a car travels 150 kilometers in 2 hours, the speed would be:
\[ \text{Speed} = \frac{150 \text{ km}}{2 \text{ hours}} = 75 \text{ km/h} \]
### Units:
Make sure the units for distance and time match, so your speed is in the correct units (e.g., km/h, m/s).
