Final answer:
Patric ran 4 1/5 kilometers in a week.
Step-by-step explanation:
To find out how much Patric ran in a week, we need to multiply the distance he ran each day (3/5 of a kilometer) by the number of days in a week (7).
3/5 * 7 = 21/5 = 4 1/5 kilometers
Therefore, Patric ran 4 1/5 kilometers in a week.
