Task 1 from workshop 6

Question: In a remote area of Australia, the Royal Flying Doctor Service has an aircraft base located at E and another aircraft base located at F. All emergency calls are received at a central call centre and are then transferred to the closest aircraft base. The map of the area shows the position of the two aircraft bases.You need to divide the area into two regions so that any emergency is responded to from the nearest aircraft base.The scale on the map is ''grid square side = 20 km''. 1 . Move the ''Radius'' slider a little to the right to see two small circles. A circle is a set of points the same distance from its centre.The two circles have the same radius length. All the points on the circle on the left are the same distance from E as all the points on the circle on the right are from F. We are looking for points that are the same distance from both points (aircraft bases). 2. Move the ''Radius'' slider more to the right until the circles intersect at one point. When the two circles intersect at one point we have the midpoint of E and F. 4. Move the ''Radius'' slider more to the right so the circles intersect at two points, L and K.These points are the same distance from both aircraft bases. 5. Move the slider all the way to the right. 6. Use ''Hide Some of the Workings'' to hide some of the workings. 7. Use ''Hide Rest of the Workings'' to hide the rest of the workings.
