Your family decides to take a long trip for the summer. You will be riding in the car while it moves at a fairly constant rate (about the same speed). The longer you are in the car, the further you travel on your trip. What is the dependent variable and why

The dependent variable is the distance traveled on the trip. This is because it depends on the independent variable, which is time spent in the car (assuming a relatively constant speed). As time increases, the distance traveled also increases. Therefore, distance traveled is the variable that is dependent on the amount of time spent in the car.
