Rasik walked 20 m towards north. Then he turned right and walks 30 m. ...
Starting Position
Rasik starts at a certain point, and we need to determine his final position and direction after following the given instructions.
Step 1: Moving North
Rasik walks 20 m towards the north. This means he moves straight ahead without changing direction.
Step 2: Turning Right
After walking 20 m north, Rasik turns right. This means he changes his direction from north to east.
Step 3: Moving East
Rasik walks 30 m in the east direction.
Step 4: Turning Right
After walking 30 m east, Rasik turns right again. This means he changes his direction from east to south.
Step 5: Moving South
Rasik walks 35 m towards the south.
Step 6: Turning Left
After walking 35 m south, Rasik turns left. This means he changes his direction from south to east.
Step 7: Moving East
Rasik walks 15 m towards the east.
Step 8: Turning Left
After walking 15 m east, Rasik turns left again. This means he changes his direction from east to north.
Final Position
Rasik's final position is 15 m north and 15 m east from the starting point.
Explanation
To determine the final position, we can draw a diagram or use a coordinate system. Let's assume the starting point is the origin (0,0) on a coordinate plane.
- Rasik moves 20 m towards the north, so his position becomes (0,20).
- After turning right and walking 30 m east, his position becomes (30,20).
- Then, he turns right again and walks 35 m towards the south, so his position becomes (30,-15).
- After turning left and walking 15 m east, his position becomes (45,-15).
- Finally, he turns left again and walks 15 m towards the north, so his final position is (45,0).
Therefore, Rasik is 45 m east and 0 m north from the starting position.
Answer
The correct answer is option D) 45 m East.
