Final answer:
Peter ran a total of 4 kilometers.
Step-by-step explanation:
To find the total distance Peter ran, we need to multiply his daily distance by the number of days he ran. Peter runs (2/3) kilometer each day for 6 days. So, to find the total distance, we can write:
Total Distance = Daily Distance * Number of Days
Total Distance = (2/3) * 6 = 4 kilometers
Therefore, Peter ran a total of 4 kilometers.
