**Part 1: Distance covered per hour**
Given:
- Distance covered by the car: 128.25 km
- Time taken: 9.5 hours
To find the distance covered per hour, use the formula for average speed:
\[ \text{Average speed} = \frac{\text{Total distance}}{\text{Total time}} \]
\[ \text{Average speed} = \frac{128.25 \text{ km}}{9.5 \text{ hours}} \]
\[ \text{Average speed} = 13.5 \text{ km/h} \]
Therefore, the distance covered by the car in 1 hour is **13.5 km**.

**Part 2: Petrol consumption**
Given:
- Petrol consumption rate: 0.8 liters per km
- Distance covered: 128.25 km
To find the total petrol required for the ride, multiply the distance covered by the petrol consumption rate:
\[ \text{Petrol required} = \text{Distance} \times \text{Petrol consumption rate} \]
\[ \text{Petrol required} = 128.25 \text{ km} \times 0.8 \text{ liters/km} \]
\[ \text{Petrol required} = 102.6 \text{ liters} \]
Therefore, the amount of petrol required for the ride is **102.6 liters**.
