Question

Elena and tyler are on a cross country team. Elenas didtance for training run is given in the equation y=8.5x while x is miles and y is time and tyler is 0.125 miles per minute. Who rsn faster during the training run?

Answer 1

Elenas runs faster than Tyler.

Explanation:

Given:

Elenas distance during the training run is given as:

`y=8.5x`

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}`

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.
