Answer:
Justin's displacement is 12.65 km.
Step-by-step explanation:
Since Justin rides 12 km south, then 4 km west, his displacement can be determined by applying Pythagoras theorem to the sketch of his journey. Let his displacement be represented by s,
= 
+ 
= 
+ 
= 16 + 144
= 160
⇒ s = 
= 12.6491
s ≅ 12.65 km
Justin's displacement is 12.65 km.
-31/15 is the correct answer
Answer:
