Answer:
4.47 km
Explanation:
Drawing the path of the van we get a shape with two exposed points A and E. If we draw a line from point E perpendicular to AC we get point B. This gives us a right angled triangle AEB.
From Pythagoras theorem
AE² = AB² + EB²
[tex]AE=\sqrt{AB^2+EB^2}\\\Rightarrow AE=\sqrt{2^2+4^2}\\\Rightarrow AE=\sqrt{20}\\\Rightarrow AE=4.47\ km[/tex]
Hence, the van is 4.47 km from its initial point
