Video Summary

The video discusses determining which of five runners ran the fastest using a plotted graph with time on the horizontal axis and distance on the vertical axis. The speed is derived from the slope of the line connecting each runner's point to the origin, as speed equals distance divided by time. The steepest slope indicates the fastest speed. By assessing the slope's steepness, Daniel is identified as the fastest runner since his line has the steepest slope, indicating the greatest speed. Thus, the answer is Daniel.
