Answer:

[tex]\sqrt{21}\ km[/tex] or  [tex]4.58\ km[/tex]  

Step-by-step explanation:

we know that

Applying Pythagoras' Theorem, calculate how many kilometers eastward Santos walked

so

Let

x----> quantity of kilometers eastward that Santos walked

[tex]x^{2}=5^{2}-2^{2}[/tex]

[tex]x^{2}=21[/tex]

[tex]x=\sqrt{21}\ km[/tex] ----> exact value

[tex]\sqrt{21}=4.58\ km[/tex]  -----> approximate value
