In a physics experiment, a student filled a burette with water up to a level of 15ml. The student ran out 3 drops of water each of volume 2cm3
Three islands P,Q,R and S are on an ocean such that island Q is 400Km on a bearing of 0300 from island P. island R is 520Km and a bearing of 1200 from island Q. A port S is sighted 750Km due South of island Q.
(a) Taking a scale of 1cm to represent 100Km, give a scale drawing showing the relative positions of P,Q,R and S. (4mks)
(b) Use the scale drawing to:
Find the bearing of:
i. Island R from island P (1mk)
ii. Port S from island R (1mk)
(c) Find the distance between island P and R (2mks)
