To determine who ran 212 km in 45 minutes, we would typically use the graph that you mentioned, but since I cannot see the graph, I can't directly assess the data points shown.
However, you can calculate the rate of running for each friend using the formula:
\[ \text{Rate} = \frac{\text{Distance (km)}}{\text{Time (min)}} \]
If you provide the data points from the graph or the rates for each of the friends, I can help you identify who ran 212 km in 45 minutes. Otherwise, please check the rates listed in your graph to see if any match the calculation for running 212 km in 45 minutes.
Just for clarity, here’s how you would calculate that rate:
\[ \text{Rate} = \frac{212 \text{ km}}{45 \text{ minutes}} \approx 4.71 \text{ km/min} \]
You would then compare this rate with the rates of Bella, Paul, Greg, and Ruby as plotted on the graph.
