Final answer:
The world record distance of 23,697 miles, when rounded to the nearest ten thousand, is 20,000 miles, corresponding to answer choice A.
Step-by-step explanation:
The natural gas and fuel-friendly car set a world record with a distance of 23,697 miles. To determine the distance to the nearest ten thousand miles, we look at the ten-thousands place in the number 23,697. The digit in the ten-thousands place is a 2 (indicating 20,000), and the digit in the thousands place is a 3. Since 3 is less than 5, we do not round up. Therefore, the distance rounded to the nearest ten thousand miles is 20,000 miles, which corresponds to answer choice A.
