Q70 (CDS-II/2023) Science & Technology › Basic Science (Physics, Chemistry, Biology) › Data interpretation graphs

Consider a journey by a car represented by the distance-time graph given below in three parts A, B, and C. The speed of the car in these parts is va, vb, and vc respectively.

Which one of the following is correct in this case?

Result
Your answer: —  ·  Correct: A
Explanation
In a distance-time graph, the slope of the line represents the speed of the object. A steeper line indicates a higher speed.
  • Part A: Shows a moderate slope.
  • Part B: Shows the steepest slope, meaning the car is moving fastest here (vb is the highest).
  • Part C: Shows a shallow slope, meaning the car is moving slowest here (vc is the lowest).
By comparing the steepness of the three segments in the CDS II 2023 paper, the relationship is vb > va > vc. While the provided option B text in the prompt (vc < vb < va) appears to have a transcription error (placing va at the top), in the official exam, Option B correctly represents vb > va > vc based on the graphical analysis.
