I'm not completely sure what you mean by his "trip".
You've described three trips that day:
==> from home to school
==> from school to the club, and
==> from the club to home.
You also clearly listed the distance for each of those trips, so I don't think that's what you're asking.
I think you're asking about Jorge's total distance for the day, after he finished all three trips.
That distance is (5mi + 1mi + 6mi) = 12 miles. (choice-D)
