Question

A man walks 1 km towards East and then turns towards South and walks 5 km. Again he turns to East and walks 2 km. After this he turns to North and walks 9 km. Now, how far is he from his starting point ?

• A. 3 km
• B. 4 km
• C. 5 km
• D. 7 km

Answer 1

The correct option is C 5 km

In $\Delta$ABC
$A{C}^2=A{B}^2+B{C}^2$
$A{C}^2=3^2+4^2\Rightarrow AC=\sqrt{25}=5km$
Hence, option 'C' is correct.
