Consider a journey by a car represented by the graph given below in three parts A, B and C. The speed of the car in these parts is v_{a}, v_{b} and v_{c} respectively:<br>Which one of the following is <strong>correct</strong> in this case?
- A. v_{a} \lt v_{b} \lt v_{c}
- B. v_{b} \gt v_{a} \gt v_{c} ✓
- C. v_{a} = v_{b} = v_{c}
- D. v_{a} \gt v_{b}; v_{a} \gt v_{c}
Correct Answer: B. v_{b} \gt v_{a} \gt v_{c}
Explanation
In a distance-time graph, the speed is represented by the slope. The slope is steepest in part B, moderate in part A, and least steep in part C, meaning v_{b} \gt v_{a} \gt v_{c}.
