Two different models of cars are on a track and accelerate to 60 mph. At the
same time, both cars slam on their
brakes. The distance it took for each
car to stop was then measured.

Identify the dependent, independent, and control variables.

The correct answer would be -

the dependent - The distance it took for each  car to stop

independent - different models of cars

control variables- accelerate to 60 mph

Explanation:

Independent variables are the variables in a study is that are get manipulated or changed to find or study the response or difference in the dependent variable. Here in this, the manipulation is a difference in the models of the cars.

The dependent variable is in this study or experiment is the distance both models took for each to stop after hitting the brakes as it depends on the independent variable.

Control variables are the variable is the variable that remains constant during the experiment so there would be no other influence than independent, in this case, speed or acceleration and same time hitting brakes are control variables.
