Amodel car travels a total distance of 81 yards during trial run. How many inches does the car travel?
The Correct Answer and Explanation is:
Correct Answer: 81 yards
The model car travels a total distance of 81 yards during the trial run.
Explanation:
Distance is a measure of how far an object moves from its starting point to its final position. In this scenario, we are told that a model car completed a trial run and traveled a total of 81 yards. Since no additional information is provided—such as changes in direction, back-and-forth movements, or multiple laps—we take the given value at face value.
The question states clearly that the car travels a total distance of 81 yards. This means that, regardless of how long it took or how fast the car moved, the entire length the car covered from start to finish adds up to 81 yards. It does not matter whether the car traveled in a straight line or took turns along the way. The total distance is the cumulative measure of its motion, not just a straight-line displacement.
In basic physics and mathematics, distance is a scalar quantity, which means it has magnitude but no direction. Therefore, even if the car went in loops or retraced some of its steps, the total distance would still include all of those movements.
It is also important to distinguish distance from displacement. Displacement refers to the shortest path between the starting and ending points, considering direction. Since the question only asks for total distance, we focus solely on how much ground the car covered during the entire run.
The correct response, therefore, remains simple and clear: the car traveled a total distance of 81 yards. No conversions, calculations, or further analysis are needed because the distance is already explicitly stated.
