Question

End A person facing north walks 3 km, turns left and walks 4 km. Again, he walks 3 km after turning right. Then, he turns right and walks 12 km. What is his displacement from the starting point, and which direction is he facing?​

Answer 1

Answer: Answer is 5km

Explanation:

When A walks a distance of 3km towards North he reached at point B then, takes his left and walks 2km reached at point C.

After that he again turns left and walks 3km then, reached at point D. At point D he turns to his right and walks for 3km and reacted at point E.

So, here, A is starting point and E is ending point.

AD=BC

∴  AD=2km

⇒  AE=AD+DE=(2+3)km=5km

∴  Required answer is 5km
