Because usually position is a function of time rather than the other way around. Changes in time result in changes in location. Changes in location do not cause changes in time.
independent
The independent variable, in this case time, is on the horizontal axis of a speed graph.
To create a graph with an independent variable, you would typically plot the independent variable on the x-axis and the dependent variable on the y-axis. For example, if you're studying the effect of time on distance traveled, time would be the independent variable (x-axis) and distance would be the dependent variable (y-axis). You can then plot data points based on your observations and connect them to visualize the relationship between the two variables.
On a distance vs. time graph, time is usually the independent variable presented on the X axis in the Cartesian Coordinate System. The dependent variable would be distance, and would be presented on the Y axis.
The slope of a line on a position vs. time graph would represent the a velocity of the object being described.
In a position versus time graph, time is typically considered the independent variable because it is controlled by the experimenter and is used to measure the dependent variable, which is position. The position of an object (dependent variable) changes over time (independent variable), and thus position is plotted against time to show how it varies based on the passage of time.
Time is an independent variable because it is affected only by when you decide to stop to read its position (not affected by the position). However, time is a dependent variable since the time you record it affects its result. In simpler terms, independent variable is something you can change to alter the dependent variable. You can change the time (0s to 15s etc.) but you cannot change the position.
independent
The independent variable, in this case time, is on the horizontal axis of a speed graph.
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
To create a graph with an independent variable, you would typically plot the independent variable on the x-axis and the dependent variable on the y-axis. For example, if you're studying the effect of time on distance traveled, time would be the independent variable (x-axis) and distance would be the dependent variable (y-axis).

The independent variable (such as time) is places on the x-axis of a graph. Always place the things that will never change on the x-axis. The dependent variable is then placed on the y-axis. The difference between the independent and dependent variable is that the independent variable in an experient does not change it is what stays constent, it is what is used to measure the dependent variable. On the other hand the dependent variable is what the experiment is testing for and what depends on the independent variable.
A dependent value in a velocity-time graph is the velocity of the object being measured at different points in time. It is the vertical axis value that is influenced by the independent variable, time, on the horizontal axis. The dependent variable changes as a result of the independent variable.
The independent variable is the (x) axis or horizontal part of a graph. The dependant is the vertical (y) axis. The independent variable can change but the dependant can't, such as x=nightly sleep time and y=hours in 1 day.
Time is nearly always the independent variable, which are normally plotted on the horizontal axis.
