The amount of distance that was covered by this person is equal to 4 kilometers.
The displacement from the starting point is equal to 2 kilometers to the right.
In Science, distance can be defined as the amount of ground that is covered (travelled) by a physical body or object over a particular period of time and speed, irrespective of its direction, starting point or ending point.
In this scenario, the total distance covered in a straight line by this person can be calculated by adding the distance he ran towards the right direction to the distance he ran towards the left direction as follows:
Distance = xf + x₀
Distance = 3 + 1
Distance = 4 kilometers.
On the other hand (conversely), the displacement of this person would be calculated by subtracting the distance he covered when running back from the distance he covered when running towards the right direction as follows:
Displacement = xf - x₀
Displacement = 3 - 1
Displacement = 2 kilometers to the right.
