Answer :
The total distance of the student is 37 m. The total displacement of the student is 7 m south.
What is distance?
The distance of an object is the total space covered by the object. It is scalar quantity because it has only magnitude with no direction.
The total distance covered by the student is calculated as follows;
distance = 15 m + 7 m + 15 m
distance = 37 m
What is displacement?
The displacement of an object is the change in the position of the object. Displacement is vector quantity because it has both magnitude and direction.
The displacement of the student is calculated as follows;
displacement = space between the 15 m west and 15 meter east = 7 m south.
Thus, the total distance of the student is 37 m. The total displacement of the student is 7 m south.
