Answer:
Elenas runs faster than Tyler.
Explanation:
Given:
Elenas distance during the training run is given as:
![y=8.5x](https://img.qammunity.org/2020/formulas/mathematics/high-school/7vif2o99qzugo1n1wk6ay5ln1e1vfefige.png)
Here, the slope of the line is 8.5 which is nothing but the speed of Elenas during training run.
Speed =
![8.5\textrm{ mi/h}=(8.5)/(60)=0.142\textrm{ mi/min}](https://img.qammunity.org/2020/formulas/mathematics/high-school/c3jmzecfurud0ok4hzjh48l6zuw72emvf9.png)
Therefore, speed of Elenas is 8.5 miles per hour or 0.142 miles per minute.
Speed of Tyler is 0.125 miles per minute.
Therefore, speed of Elenas is greater and hence faster.
