Question

Ravi starts walking towards North. After walking $15$ m he turns towards South. After walking $20$ m, he turns towards East and walks $10$ m. He then turns towards North and walks $5$ m. How far is he from his original position and in which direction?

• A. $10$ m, North
• B. $10$ m, South
• C. $10$ m, East
• D. $10$ m, West

Answer 1

The correct option is C $10$ m, East

Ravi walks 15 km North, he then turns South and walks 20 Km South.

Basically, he turns in opposite direction and moves 5 km more, so he is 5 km South from the starting point.

Then he turns East and walks 10 km, so he is walking towards South-East.

And then he again turns towards North and walks 5 km.

Thus he comes back in the same line from the starting point towards East.

Hence, Ravi is 10 km towards East from his original position.
