A boat sails in a straight line from Aardvark Island on a bearing of

060 °

. When the boat has sailed

8 k m

it reaches Beaver Island and then turns to sail on a bearing of

150 °

. The boat remains on this bearing until it reaches Crow Island,

12 k m

from Beaver Island. On reaching Crow Island the boat’s pilot decides to return directly to Aardvark Island. Calculate the length of the return journey

Jason stands in the corner of a very large field. He walks , on a bearing of

030 °

a distance of

d

meters. Jason then change direction and walks twice as far on a new bearing of

120 °

. At the end of the walk Jason calculates both the distance he must walk and the bearing required to return to his original position. Given that the total distance walked is
