To find out who ran 2.12 km in 45 minutes based on the ratio of distance to time, we need to calculate the rate (speed) in kilometers per minute.
First, let's calculate the speed for someone who runs 2.12 km in 45 minutes:
- Calculate the rate: \[ \text{Rate} = \frac{\text{Distance}}{\text{Time}} = \frac{2.12 \text{ km}}{45 \text{ min}} \approx 0.04711 \text{ km/min} \]
Now, we can look at the rates provided in the graph, which are typically expressed as distances over time in order to identify who corresponds to this rate.
However, since I cannot see the graph mentioned, if you compare the calculated value to the points plotted on the graph, the person who matches this rate is the person who ran 2.12 km in 45 minutes.
Please refer to the graph and find the person associated with a rate of approximately 0.04711 km/min. Based on the choices you provided (Bella, Ruby, Paul, or Greg), identify the correct name from the graph.
