$\sqrt{21}\ km$ or $4.58\ km$

Step-by-step explanation:

we know that

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

Let

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

$x^{2}=5^{2}-2^{2}$

$x^{2}=21$

$x=\sqrt{21}\ km$ ----> exact value

$\sqrt{21}=4.58\ km$ -----> approximate value
