To determine who ran 2.12 km in 45 minutes based on the given information, we need to look at the plotted points for each participant:
- Bella: 3.5 km in 45 minutes
- Ruby: 2.5 km in 40 minutes
- Greg: 2.5 km in 45 minutes
- Paul: 1 km in 25 minutes
From the options provided, none of the participants specifically ran 2.12 km in 45 minutes. However, if we consider that the question may relate to a participant with a similar performance, we see that Greg ran 2.5 km in 45 minutes, which is the closest distance to 2.12 km within the given time frame.
Thus, while the answer isn't exactly 2.12 km at 45 minutes, the best response based on the data shown in the graph would be:
Greg.
