Ok, i'm going into my local town tomorrow, which is roughly 1.5 miles away. I can either walk or cycle there. Same distance.

We all know that lower intensity exercise uses more fat and less carbs, and higher intensity exercise uses more carbs and less fat for fuel. Given that the walking method would take around 3 times longer than cycling there... which method would have burnt the most fat once the journey was complete? Even though cycling would be burning more fat per minute, i'd be cycling for a much shorter time than if i were walking.

Anyone care to elaborate?
