To calculate the velocity, we use the formula for velocity:

$\text{Velocity} = \frac{\text{Distance}}{\text{Time}}$

Given:

• Distance = 75 miles
• Time = 1.5 hours

$\text{Velocity} = \frac{75 \, \text{miles}}{1.5 \, \text{hours}} = 50 \, \text{miles per hour (mph)}$

Since the car traveled north, we specify the direction in the velocity. Thus, the correct answer is:

50 miles per hour NORTH

Velocity always includes both the magnitude (speed) and the direction.
