Final answer:
To find out how many miles you can expect to drive in a year, divide the total miles driven by the number of years. In this case, you can expect to drive around 10,000 miles in a year.
Step-by-step explanation:
To find out how many miles you can expect to drive in a year, you can divide the total miles driven by the number of years. Let's assume an average of 10,000 miles driven in a year.
So, dividing 139,309 miles by 10,000 miles will give you approximately 13.93 years.
Therefore, in a year you can expect to drive around 10,000 miles (option a).
