A marketing executive goes on his field work and walks 2 km North, then he turns West and walks 6 km, then he turns North and walks 7 km, and then he turns to his right and walks 6 km. Where is he now with respect to his starting position?

Let the marketing executive starts from point A and walks 2 km North, then he turns West and walks 6 km to reach C, then he turns North and walks 7 km to reach point D, and then he turns to his right and walks 6 km eastwards to finally stop at point E.

=> AE = $$2+7=9$$ km

$$\therefore$$ He is 9 km north with respect to his starting position.
