## Question

$A$ and $B$ are two lifeboat stations on a North-facing coast, $B$ being $\quantity{6}{km}$ due East of $A$. A distress call from a ship is received simultaneously at both stations. The bearing of the call from $A$ is measured to lie between $060^\circ$ and $065^\circ$. The bearing of the call from $B$ is measured to lie between $330^\circ$ and $335^\circ$. By means of a scale drawing on squared paper find as accurately as possible

1. the least and greatest possible distances of the distressed ship from $B$, and
2. the area that may need to be searched, giving your answer in square kilometers to two significant figures.
