1. **State the problem:** A species of goose travels 550 miles in 10 hours. We need to find its rate of movement. 2. **Formula used:** The relationship between distance, speed, and time is given by the formula: $$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$$ 3. **Apply the formula:** Substitute the given values: $$\text{Speed} = \frac{550}{10}$$ 4. **Simplify the fraction:** $$\text{Speed} = \frac{\cancel{550}}{\cancel{10}} = 55$$ 5. **Interpret the result:** The speed is 55 miles per hour. **Final answer:** The goose is moving at 55 miles per hour.
