Final answer:
The average velocity of a car that traveled 75 kilometers north in 1.5 hours is 50 km/h North.
Step-by-step explanation:
The velocity of a car that traveled a total of 75 kilometers north in 1.5 hours can be calculated using the formula for average velocity. Average velocity is defined as the total displacement divided by the total time taken. In this case:
Vavg = (total displacement) ÷ (total time)
Vavg = (75 km) ÷ (1.5 h)
Vavg = 50 km/h North
This means that the average velocity of the car was 50 kilometers per hour in the northern direction.
