Final answer:
Samira and her dad disagree on the car's speed due to differing frames of reference.
Explanation:
Samira and her dad disagree about the car's speed because they are in different frames of reference. Samira, sitting in the back seat, uses the passing cars as a reference point, while her dad, driving the car, uses the passing buildings as a reference point. This difference in reference frames leads to their disagreement.
