1. The problem asks for the time it takes Percy to ride 10 kilometers at a speed of 20 kilometers per hour. 2. We use the formula for time: $$\text{time} = \frac{\text{distance}}{\text{speed}}$$ 3. Substitute the given values: $$\text{time} = \frac{10}{20} = 0.5 \text{ hours}$$ 4. Convert hours to minutes by multiplying by 60: $$0.5 \times 60 = 30 \text{ minutes}$$ 5. Therefore, it will take Percy 30 minutes to ride from home to the station.
