Mark is part of your group on the orienteering exercise. He ends up in a different place than the rest of the group. The directions to the location were 45 degrees, 200 feet. He tells you that he set up his compass to point NE, held his compass flat, turned his body until the needle lined up with the "red shed". He calculated that he had to walk at 540 paces based on his pace of 2.7 feet per step. Where did he go wrong?
