Answer:
Elenas runs faster than Tyler.
Step-by-step explanation:
Given:
Elenas distance during the training run is given as:
[tex]y=8.5x[/tex]
Here, the slope of the line is 8.5 which is nothing but the speed of Elenas during training run.
Speed = [tex]8.5\textrm{ mi/h}=\frac{8.5}{60}=0.142\textrm{ mi/min}[/tex]
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.
