Which of the following is a plausible feature of the X-axis in a speed-time graph?

Explanation:
In a speed-time graph, time is the horizontal axis because the graph shows how speed changes as time passes. The speed value at each moment is read from the vertical axis, so speed is the dependent variable and time is the independent variable. This setup lets you see how fast the object is moving at any given moment, and it also links to other ideas like acceleration (slope) and distance (area under the curve). If the bottom axis tried to show distance or area, or if speed were plotted along the bottom, it wouldn’t reflect how speed varies with time. So the X-axis represents time.
