Final answer:
To calculate the average miles Tina traveled per day on her trip, divide the total miles (4,096) by the days (8) to get 512 miles per day.
Step-by-step explanation:
To find the average miles Tina traveled per day during her trip, we need to divide the total miles by the number of days of her trip. So, we take the total distance of 4,096 miles and divide it by the 8 days Tina took to travel that distance.
Calculation:
4,096 miles / 8 days = 512 miles/day therefore, the unit rate representing the average miles Tina traveled per day during her trip across the country is 512 miles per day.
