You can put this solution on YOUR website!
Let +d+ = distance in miles hiked on the first day
All the distances must be in miles for the solution to work
--------------------
+2d+ = distance hiked on 2nd day
+d+%2B+2d+%2B+12+ = distance hiked on 3rd day
-------------------------------------------
+d+%2B+2d+%2B+d+%2B+2d+%2B+12+
+6d+%2B+12+ = distance hiked on 3 day trip
