To convert 280 km/h (kilometers per hour) to m/s (meters per second), follow this process:

1. **Recall the conversion factors:**
   - 1 kilometer = 1000 meters
   - 1 hour = 3600 seconds

2. **Set up the conversion:**
   \[
   \text{Speed in m/s} = 280 \, \text{km/h} \times \frac{1000 \, \text{m/km}}{3600 \, \text{s/h}}
   \]

3. **Simplify the calculation:**
   \[
   \text{Speed in m/s} = 280 \times \frac{1000}{3600} = 280 \times \frac{5}{18}
   \]

4. **Perform the multiplication:**
   \[
   \text{Speed in m/s} = 280 \times 0.2778 \approx 77.78 \, \text{m/s}
   \]

So, **280 km/h is approximately 77.78 m/s**.
