SNOWED IN
Nick and his sleigh are stranded in the woods. He is desperate to get back to his cabin in time for Christmas to deliver presents to his children. His usual route would take him in a straight line directly to his cabin, but a snow drift is blocking his way. Instead he must take a lengthy diversion. Nick sledges three kilometres east to the frozen lake, before turning his sleigh 135° clockwise and travelling 1,300 metres to the reindeer stable. According to his sat-nav he is now 500 metres further south than the frozen lake. Nick then rotates his sleigh 45° clockwise, and travels 1,275 metres to his cabin. How much further has Nick had to travel due to the diversion?
