Answer:

Magnitude of the overall velocity = 36.06 m/s

Explanation:

30 m/s West in vector form = -(30î) m/s

20 m/s South in vector form = -(20j) m/s

The overall velocity = (- 30î - 20j) m/s

Magnitude of the velocity (x,y) = √(x² + y²)

Magnitude of the velocity = √((-30)² + (-20)²) = 36.06 m/s
