To determine who ran 2.12 km in 45 minutes based on the graph, we need to look at the plotted points for each participant:
- Bella: 3.5 km at 45 minutes
- Ruby: 2.5 km at 40 minutes
- Greg: 2.5 km at 45 minutes
- Paul: 1 km at 25 minutes
It appears that none of the participants ran 2.12 km in exactly 45 minutes. However, looking for the one who ran the closest at that time, we should consider:
- Bella ran 3.5 km in 45 minutes.
- Greg ran 2.5 km in 45 minutes.
Neither of these participants matches the 2.12 km. Based only on the points on the graph, none of the names match the criteria of running 2.12 km in 45 minutes. However, the question could perhaps imply a rounding or a miscommunication of the distance.
If we consider the options based solely on the available data:
The one who ran the distance closest to 2.12 km in 45 minutes is Greg at 2.5 km.
Therefore, the most suitable answer based on the graph is: Greg.
