Based on the information provided from the graph, none of the participants ran 212 km in 45 minutes. In fact, the distances indicated on the graphed lines only reach a maximum distance of 5 km (as that is the distance of the run) and are plotted at various points up to 3.5 km for Bella at that time.
If the question were to determine the distance run by each participant at 45 minutes, we see:
- Bella reached 3.5 km in 45 minutes.
- Ruby reached 2.5 km in 40 minutes.
- Greg reached 2.5 km in 45 minutes.
- Paul only reached 1 km in 25 minutes.
None of the participants ran 212 km in 45 minutes according to the details of the graph. The maximum distances they achieved at corresponding times is far below 5 km, and no one is shown to have a speed or capacity to cover such a distance.
If the intent is to select the person who exhibited the highest performance at 45 minutes as demonstrated on the graph for practical markers, we would consider Bella first, as she covered the highest distance of 3.5 km at that time.
If you need a response based solely on the original question focused on the graph's context, it would be:
Bella
