During the same interval, it is observed that a train travels the same distance as does a lorry. The two vehicles therefore have the same
Answer Details
The correct answer is "average speed".
Average speed is the total distance covered by an object over a period of time, whereas average velocity is the displacement of an object over a period of time. Since both the train and the lorry travel the same distance during the same interval, they must have the same average speed. It is important to note that this does not necessarily mean that they have the same average velocity, as their displacements could differ.
