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

 from the burette into a beaker. Determine the final reading of the burette.                                                                                                                                                                                               (2 marks)

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)
