  Question 10 (b):
  Diagram 10.2 shows a polygon HABCD and a square JKLM.
  (i) Under a transformation, polygon HABCD will be transformed such that the image will be placed inside the square JKLM. The image formed based on the following conditions:
  
  Suggest one possible complete transformation.
  (ii) Using the transformation that you have suggested in (b)(i), mark the new position of point W in Diagram 10.2.

  Question 10 (c):
  Diagram 10.3 shows a car route from P to S. The driver starts the journey from P. When he reaches R, he turns back and travels ¼ the distance of P to R and then he continues to S to finish his journey.
  
  Table 10 shows the distance between the destinations.
  
  Assuming that the distance travelled in the journey when the driver turns back as a wasted distance, calculate the fraction of the wasted distance to the distance of the whole journey.
  
  Solution:
