Revision Race: Question 2 Team: A – A* Revision Race: Question 2 Team: A – A* This diagram shows a plan of a room ABCD. Security sensors are installed in corners B and D. At B the sensor can detect movement a distance 10m away. The sensor at D is set up so that the two sensors will cover the whole room. Make an accurate scale drawing and use it to work out the minimum distance that the sensor at D should be set for. A and B are two buoys in the sea off the coast near Morecambe. B is 500m due east of A. (a) Use a scale of 1cm to 50m to make an accurate drawing of A and B. (b) Amy sails her boat so that she is the same distance from A as she is from B. On your diagram construct the locus of points to represent the course Amy sails.
