From the table in the image, the frequency for the people who use a car is 12. The bar graph's partial axes are shown, but we can't see the full scale clearly.

To determine how many rows tall the bar for "Car" should be, we need to know the scale of the graph. If the graph uses rows representing a certain number of people per unit (e.g., 1 row = 2 people, 1 row = 1 person, etc.), we can divide the frequency of car users (12) by the number of people each row represents.

Assuming the scale is 1 row = 2 people (common for simpler graphs), the bar for the car would be: $\frac{12 \text{ people}}{2 \text{ people/row}} = 6 \text{ rows}$

Thus, the bar for the "Car" would be 6 rows tall.

Let me know if you'd like more information or have any further questions!

Here are five related questions:

1. How tall would the bar for "Bus" be if the same scale is used?
2. What would the total number of rows be if you plotted bars for all methods of travel?
3. How would the bar heights change if the scale was 1 row = 1 person?
4. How can you calculate the total number of travelers using the frequency data?
5. What would the tallest bar be and how many rows would it have?

Tip: Always check the scale of the graph before plotting to ensure accurate bar heights!
