Displacement of a car

Classical Mechanics Level 1

A car at point $A$ on a straight road goes west for $20$ seconds, arriving at point $B$ which is $200$ m away from $A.$ The car then heads back to the east for $30$ seconds, arriving at point $C$ which is $800$ m away from $B.$ What is the displacement of the car from point $A$ ?

Assume that $+$ is east and $-$ is west.

-600 m -800 m +800 m +600 m
