Final answer:
To determine how many miles the family should drive each day, divide the total distance of 1,145 miles by the four days of the trip, resulting in an average of approximately 286.25 miles per day.
Step-by-step explanation:
The question asks us to find the distance that the family should drive each day during their trip. To calculate this, we divide the total distance of the trip by the number of days they plan to travel. Given that the trip from Austin, Texas, to Tampa, Florida, is 1,145 miles and lasts four days, we perform the following division: 1,145 miles ÷ 4 days = 286.25 miles per day.
This means that the family should aim to drive approximately 286.25 miles each day to evenly spread out their traveling distance over the four days. This method of dividing the total distance by the total number of days gives us the average miles per day they need to travel.
