Foundation November 2019 Paper 1 Q12
12. The diagram shows the position of two aeroplanes, \(P\) and \(Q\).
There is a radar station at \(R\).
The scale is 1 cm represents 0·5 km.

On screen this diagram may not be shown at actual size. To measure it, use the question paper (PDF) printed at 100%.
(a)
\(R\) is nearer to \(Q\) than it is to \(P\).
How much nearer? [2]
(b) Measure and write down the bearing of \(R\) from \(P\). [1]
(c)
There is an airport which is 2·5 km from \(R\) and to the south-west of \(Q\).
Mark the position of the airport with a cross on the diagram. [2]
