Journey Graphs


1. The problem asks which graph(s) can represent a journey from point P to point Q based on distance vs. time graphs. 2. A journey from P to Q means distance should start at P's distance at time zero and increase or stay constant over time until reaching Q's distance. Distance cannot decrease because that would imply moving backward. 3. Graph A shows a steadily increasing distance from P to Q over time, which is consistent with a journey moving forward without going backward. 4. Graph B shows a jagged line with some dips or plateaus, meaning the distance sometimes decreases or stays the same. Distance decreasing is not possible in a forward journey, so Graph B cannot represent the journey. 5. Graph C shows two lines forming a triangle, with one line going downward from Q and another upward from P meeting at some time. The downward line means distance decreases, which is impossible in a forward journey, so Graph C cannot represent the journey. 6. Therefore, only Graph A can represent a journey from P to Q. 7. Completing the sentences: Graph B cannot represent a journey from P to Q because the distance decreases at some points, which is impossible in a forward journey. Graph C cannot represent a journey from P to Q because the distance decreases from Q to the meeting point, which cannot happen in a forward journey. Final answers: - Graph A can represent the journey. - Graph B cannot. - Graph C cannot.
