It sounds like vector A is pointing south and vector B is pointing north.

Furthermore it seems like the magnitude of A is 40 meters, and B is 12.50 meters

Because the vectors point in completely opposite directions, we subtract their magnitudes: 40.0-12.50 = 27.5

The result is made negative because the magnitude pulling south (40) is greater than the magnitude pulling north (12.5)
Think of it like vector A winning the tug-of-war.

Another way to think of it is to say -40 + 12.5 = -27.5

Answer: B. -27.5 m
