First, draw the appropriate diagram to scale using a relationship such as 1 cm = 1 km, and you will see a space remaining between where the Matons began their trip and where they ended. Because you are solving this exercise graphically, measure with a ruler the length of the remaining space and convert your measurement back into km. This is the resultant displacement. (Hint: You may find it easier to use graph paper for your drawing so that you can have 1 km equal to a certain number of squares.)
Answer is 450 km, as measured with a ruler.
