A port B is on a bearing of #080^0# from a port A and at a distance of 95 km. A submarine is stationed at a port D, which is on a bearing of #200^0# from A and a distance of 124 km from B. A ship leaves B and moves directly
southwards to an island P, which is on a bearing of #140^0# from A. The submarine at D on realizing that the ship was heading for the island P, decides to head straight for the island to intercept the ship.Using a scale 0f 1 cm to represent 10 km, make a scale drawing showing the relative positions of A, B, D, P. Hence find
(i) The distance from A to D
(ii) The bearing of the submarine from the ship when the ship was setting off from B
(iii) The bearing of the island P from D
(iv) The distance the submarine had to cover to reach the island P
