Three points P, Q and R are on a level ground. Q is 240 m from P on a bearing of #230^0#. R is 120 m to the east of P. a) Using a scale of 1 cm to represent 40 m, draw a diagram to show the positions of P, Q and R
b) Determine
i) The distance of R from Q
ii) The bearing of R from Q
c) A vertical post stands at P and another one at Q. A bird takes 18seconds to fly directly from the top of the
post at q to the top of the post at P.Given that the angle of depression of the top of the post at P from the top of the post at Q is #9^0#,
Calculate:
i) The distance to the nearest metre, the bird covers
ii)The speed of the bird in Km/h.
