Sanjeev walks 10 meters towards the South. Turning to the left, he walks 20 meters and then moves to his right. And moving a distance of 20 meters, he turns to the right and walks 20 meters. Finally, he turns to the right and moves a distance of 10 meters. How far and in which direction is he from the starting point?
Answer with explanationAnswer: Option B
The movements of Sanjeev from A to F are as shown in Figure Clearly,
Sanjeev’s distance from starting point A
= AF = (AB + BF) = AB + ( BE – EF ) = AB + (CD – EF)
= [10 + (20 – 10)] m = (10 + 10) m = 20 m.
Also, F lies to the South of A. So, Sanjeev is 20 meters to the south of his starting point.
