To determine who ran 212 km in 45 minutes based on the provided graph, we need to analyze the rates of each friend. The rate can be calculated as:
\[ \text{Rate} = \frac{\text{Distance (km)}}{\text{Time (min)}} \]
In this case, we can compute the rate for the person who ran 212 km in 45 minutes:
\[ \text{Rate} = \frac{212 \text{ km}}{45 \text{ min}} \approx 4.711 \text{ km/min} \]
You will need to examine the graph to see which friend has a corresponding point that shows a rate close to 4.711 km/min. If you can identify that point on the graph, then you can name the person based on that data.
Since I do not have access to the graph itself, I recommend you look for the point (or calculated rate) that matches approximately 4.71 km/min to identify the appropriate friend.
