Question 1
- The independent variable in this situation is the amount of time that has passed, as this is what determines how far the car has traveled.
- The dependent variable is the distance traveled, as it depends on the amount of time that has passed.
- I know which is which because the distance traveled depends on the amount of time that has passed, making it the dependent variable.
Question 2
- A reasonable speed for the car to travel at for most of the trip would be around 60 miles per hour. This is a common speed for highway driving and would allow the family to cover a significant distance in the 8-hour trip.
Question 3
| Time (hours) | Distance Traveled (miles) |
|--------------|---------------------------|
| 0 | 0 |
| 1 | 60 |
| 2 | 120 |
| 3 | 180 |
| 4 | 240 |
| 5 | 300 |
| 6 | 360 |
| 7 | 420 |
| 8 | 480 |
Question 4
- The graph should have "Time (hours)" on the x-axis and "Distance Traveled (miles)" on the y-axis. The gridlines should be marked at intervals of 1 hour on the x-axis and 60 miles on the y-axis. Plot the points (0,0), (1,60), (2,120), (3,180), (4,240), (5,300), (6,360), (7,420), and (8,480) on the graph.
