Answer :
The answer of the given question based on the distance is , the student is 70 meters away from the starting point.
To determine the distance from the starting point, we can follow the student's movements on a grid.
Starting at the origin, the student walks 40 meters west, then takes a left turn (which is a 90-degree counter-clockwise rotation) and walks 30 meters.
Next, the student takes a right turn (a 90-degree clockwise rotation) and walks 20 meters.
Finally, the student takes another right turn and walks 30 meters.
We can visually represent these movements using vectors.
The student's displacement vector is the vector that starts at the origin and ends at the final position.
Adding up the vectors for each movement,
we find that the magnitude of the displacement vector is 70 meters, making distance from the starting point 70 meters away.
