Which graph is not a good representation of a real-world situation?
A. Graph B is not a good representation of a real-world situation because the distance cannot increase and then decrease.
B. Graph B is not a good representation of a real-world situation because it is not a linear graph.
C. Graph A is not a good representation of a real-world situation because at a certain distance, there cannot be two different times.
D. Graph A is not a good representation of a real-world situation because at a certain time, there cannot be two different distances.
The correct answer is C. Graph A is not a good representation of a real-world situation because at a certain distance, there cannot be two different times.
Explanation: In a real-world scenario, for a given distance traveled, there should only be one corresponding time. If a graph shows that a specific distance corresponds to two different times, it suggests an inconsistency that would not occur in practice. Thus, this makes Graph A a poor representation of a realistic situation.
