Answer:
The correct option is B i.e total displacement
Draw a vector from his starting point to his ending point.
Step-by-step explanation:
Displacement:
A displacement is a vector whose length is the shortest distance from the initial to the final position of a point.
Here we will have figure below
Where
A is a initial point from where Mark walked 2 miles east till point B.
Then 1 mile to North till point C.
Therefore point C is the final point.(or end point)
Here
![Displacement=\vec{AC}](https://img.qammunity.org/2020/formulas/physics/middle-school/oxz5nuot66sairdxlbavegqinby2dh79l0.png)
So his total displacement will be given by drawing a vector from his starting point to his ending point.
