26. Which of the following statements is true?

Answer: A

Explanation:

Train A traveled at a greater average speed.

Train A's average speed was higher compared to Train B's, indicating that it covered the same distance in a shorter amount of time.

A) Train A traveled at a greater average speed.

This statement is correct because it directly indicates that Train A outperformed Train B in terms of speed, which has been confirmed by the data on their respective travel times and distances.

B) Train B traveled at a greater average speed.

This statement is incorrect as it contradicts the information provided, which clearly shows that Train B did not achieve a higher average speed than Train A.

C) The two trains traveled at equal average speeds.

This option is also incorrect because it suggests that there is no difference in the average speeds of the two trains, which is not supported by the findings that indicate Train A was faster.

D) The two trains traveled different distances, so it is impossible to compare their average speeds.

While it is true that distance may affect average speed calculations, this statement is misleading in this context because we can still compare their average speeds if both distances and times are known. Thus, this option does not accurately describe the situation.

Conclusion

Train A having a greater average speed is definitively supported by the evidence, while all other options misinterpret or misrepresent the relationship between the two trains. Options B and C directly contradict the correct answer, and option D fails to recognize that average speeds can still be compared despite differences in distance.
