Final answer:
The family took a 14-day trip and drove a total of 4,900 miles. By dividing the total miles by the number of days, it is calculated that they drove an average of 350 miles each day.
Step-by-step explanation:
The question is asking to calculate the average number of miles driven each day on a family trip from North Carolina to California and back. Since the family drove 4,900 miles in total over 14 days, we can find the daily average by dividing the total miles driven by the number of days they drove.
To calculate the daily mileage, we use the formula:
Daily miles = Total miles driven / Number of days
Daily miles = 4,900 miles / 14 days
Daily miles = 350 miles
Therefore, the family drove an average of 350 miles each day.
