Is the question:
" How far does the END of the minute hand travel?"
If so, use the formula for the circumference with
radius = 6 in
+C+=+2%2Api%2Ar+
+C+=+2%2Api%2A6+
+C+=+12%2Api+
This would be for 360 degrees, or 60 minutes for the minute hand.
distance in 20 minutes would be +%2820%2F60%29%2A12%2Api+=+4%2Api+ in
------------
The arc swept in 20 min is
+%2820%2F60%29%2A360+=+120+ degrees
