Answer :
To find the average velocity of the car, we need to use the formula for average velocity, which is:
[tex]\[ \text{Average Velocity} = \frac{\text{Total Distance}}{\text{Total Time}} \][/tex]
Let's break down the problem step-by-step:
1. Given Data:
- The car travels a distance of 30 kilometers.
- The total time taken for the journey is 0.50 hours.
- The direction of travel is due west.
2. Calculate the Average Velocity:
- Plugging in the given values into the formula:
[tex]\[ \text{Average Velocity} = \frac{30 \text{ kilometers}}{0.50 \text{ hours}} \][/tex]
3. Performing the Division:
- Dividing 30 kilometers by 0.50 hours:
[tex]\[ \text{Average Velocity} = 60 \text{ kilometers per hour} \][/tex]
4. Include the Direction:
- Since the problem specifies that the car travels due west, we include the direction in our final answer.
Thus, the average velocity of the car is:
[tex]\[ \boxed{60 \text{ km/hr west}} \][/tex]
Therefore, the correct answer from the provided options is:
4. 60. km/hr west
[tex]\[ \text{Average Velocity} = \frac{\text{Total Distance}}{\text{Total Time}} \][/tex]
