Answer:

Elena can run 3 miles per hour.

Step-by-step explanation:

Given that:

a circular running track = 1/5 mile

On this track, Elena runs completing each of the laps in 1/15 of an hour

We are to find Elena running speed.

It implies that the distance of Elena = $\dfrac{1}{5}$

Time to run each lap = $\dfrac{1}{15} \ of \ an \ hour$

Speed is the amount of distance covered in a specified period of time.

Recall that the formula for calculating speed is:

$Speed = \dfrac{distance}{time}$

$Speed = \dfrac{\dfrac{1}{5}}{\dfrac{1}{15}}$

$Speed ={\dfrac{1}{5}\times \dfrac{15}{1}$

Speed = 3miles / hour

As such, Elena can run 3 miles each hour.
