Final answer:
The incomplete question appears to be about calculating fuel economy and costs associated with a trip. Therefore, it is difficult to provide the correct option to this answer.
Step-by-step explanation:
The question seems incomplete as it is not presenting a full context or an actual query, but from the provided details, the answer can be deduced. It relates to computing quantities from measurement results and known mathematical relations with an emphasis on fuel economy and cost calculations for a specific trip.
Using an example with a 2014 Lamborghini Aventador Roadster. The conversion from 1250 kilometers results in about 776.714 miles. To calculate the fuel economy, we divide the miles traveled by the gallons used (213 Liters is equivalent to about 56.303 gallons, since 1 liter is approximately 0.264172 gallons).
For part (a), the fuel economy is calculated by dividing 776.714 miles by 56.303 gallons, which results in approximately 13.79 miles per gallon for the Lamborghini. For part (b), if gasoline costs $3.80 per gallon, the fuel cost for the trip can be computed by multiplying $3.80 by 56.303 gallons, amounting to $213.95.
