Question

Time is an independent variable, plotted along the X-axis. Distance is dependent variable, plotted along Y-axis graphs are designed to make it easy to interpret and understand numerical data. Distance-time graph is a straight line when the object is in the state of uniform motion. Slope of the graph gives the speed of the object. The distance-time graph of two trains are given below. The trains start simultaneously in the same direction

Answer 1

Explanation:

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.
