Read the following and answer any four questions from 4(I) to 4(V):. Time is an independent variable plotted along the x -axis. Distance is a dependent variable plotted along the y -axis. Graphs are designed to make it easier to interpret and understand the numerical data.Distance - time graph is a straight line ,when the object is in the state of uniform motion. Slope of a graph gives a speed of the object. The distance - time graph of two trains are given below . The trains start simultaneously in the same direction. (I)How much is B ahead of A, when the motion starts?. (ii) When and where does A meet B? (iii) What is the difference between the speed of A and B. (IV) Name the physical quantity obtained from the slope of the speed - time graph.(v). When the distance that an object travels is directly proportional to the time, it is said to travel with ------ speed

Explanation:
An independent variable is manipulated by the experimenter. Any changes made are predictable. The dependent variable reacts to changes made to the independent variable. Its changes are not controlled by the experimenter and can be hard to predict.
In this particular experiment, the scientist is measuring how the particle's distance changes over a given time. She is able to control the amount of time that she measures, but is only able to observe the distance traveled.
In the graph, the independent variable will be graphed on the x-axis.
I think it is help full
