The student returned to starting point hence the displacement is zero.

What is the displacement?

The displacement refers to the distance that is covered in a specified direction. The difference between distance and displacement is that displacement is a vector quantity while distance is a scalar quantity.

If displacement is a vector quantity, it then follows that the direction must be taken into consideration when we are talking about the displacement of the body.

Looking at the fact that the student moves backwards and returns to a position marked 20 meters another 7 seconds later, it then follows that the student returned to starting point and that the displacement is zero.
