Final answer:
To calculate the average miles run per day, divide the total miles (167.79) by the total days (59.5), which equals approximately 2.82 miles per day, so option a) is correct.
Step-by-step explanation:
To find the average miles run per day by a school track team member who ran a total of 167.79 miles over 59.5 days, we will divide the total miles run by the total number of days.
We perform the following calculation:
Average miles per day = Total miles ÷ Total days
Average miles per day = 167.79 miles ÷ 59.5 days
Average miles per day ≈ 2.82 miles per day
Therefore, option a) 2.82 miles per day is the correct answer to how many miles he averaged per day.
