Looking at the graph, we can see that line A has the steepest slope which means that line A represents the fastest speed.
Therefore, the answer is Line A.
The fastest speed is represented by the line with the steepest slope. This is because the slope of a line on a distance-time graph represents the speed of the object.
Slope refers to the steepness or incline of a line or surface and is calculated as the change in vertical distance (rise) divided by the change in horizontal distance (run). The formula for slope is:
Slope = Rise / Run
A steeper slope has a higher slope value, while a flatter slope has a lower slope value. A slope of 0 indicates a horizontal line.
