Concept:The area under a velocity-time graph represents the distance travelled by the object.Explanation:Velocity is the rate of change of displacement.When velocity is multiplied by time, it gives displacement.Mathematically, $\text{distance} = \text{velocity} \times \text{time}$.On a velocity-time graph, this product is shown as the area under the graph.Hence, this area measures the total distance covered.Answer:D. distance
