Which graph is not a good representation of a real-world situation?
A. Graph A is not a good representation of a real-world situation because at a certain time, there cannot be two different distances.
B. Graph B is not a good representation of a real-world situation because the distance cannot increase and then decrease.
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 B is not a good representation of a real-world situation because it is not a linear graph.
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 most real-world situations, especially involving time and distance, for a given distance, there can be only one corresponding time. If a graph indicates that at the same distance, there are two different times, it does not accurately reflect reality, as one distance cannot be achieved at two points in time simultaneously. This leads to contradictions in understanding the relationship being represented.
