A girl walks along a straight path to drop a letter in the letterbox and comes back to his initial position. Her displacement-time graph. Plot a velocity-time graph for the same
Distance travelled from a velocity / time graph can be calculated from area under graph, say area under (v/t) graph from 0 - 1 seconds = distance travelled after 1 second, then do 0 - 2 seconds, 0 -...
calculate distance from area under graph between equal time intervalsie 0-1 secs , 1-2 secsif v/t graph is mathematical curve, then use integration , if not then estimate.
