40 meters west ! these kinda probs can be solved easily wit a diagrammatic representation ! Pythogoras theorem can be used if it was a triangular distance calculation

Generally walking towards East is taken as positive value and walking towards West is taken as negative value.

Using this convention, we get

100m + (-60m) = 40m
