The vector quantity represents magnitude as well as direction. Velocity is a vector quantity; that means velocity has magnitude as well as direction. A wind velocity of $13\ \text{miles}$ per hour from the west means the magnitude of the wind blown is $13\ \text{miles}$ and the direction of the wind blown is from the west to east. So, this statement has both the magnitude as well as direction given. Thus, the statement is true.
