Acar travels 20 meters east in 1.0 second. the displacement of the car at the end of this 1.0 second interval is

The displacement of the car is 20 m due East.

In Physics, displacement is defined as the distance covered in a specific direction.

The difference between distance and displacement is the fact that displacement involves "direction".

Hence, distance is a scalar quantity while displacement is a vector quantity.

Therefore, for a car that traveled 20 meters east in 1.0 second. the displacement of the car at the end of this 1.0 second interval is  20 m due East.
