Answer:
17.3 blocks
Explanation:
The first path of going north is AB the second path of going east is BC the third path of going south is CD. The displacement is AD.
From Pythagoras theorem
AD² = DE²+AE²
[tex]AD=\sqrt{DE^2+AE^2}\\\Rightarrow AD=\sqrt{3^2+17^2}\\\Rightarrow AD=\sqrt{9+289}\\\Rightarrow AD=\sqrt{298}\\\Rightarrow AD=17.3\ blocks[/tex]
The displacement is the minimum distance between the initial and final point. Here, it is the distance AD.
So, the displacement of the delivery truck is 17.3 blocks.
