Answer:

The velocity is 8.93 meters/second.

Step-by-step explanation:

It is given that  Elena runs for 28 seconds and finishes at 250 meters.

Here the displacement is 250 meters and the time is 28 seconds.

We know that  [tex]V=\dfrac{\text{Displacement}}{\text{Time}}[/tex]

Substitute displacement = 250 and time = 28 in above formula.

[tex]V=\dfrac{250}{28}[/tex]

[tex]V\approx 8.93[/tex] meters/second

Hence, the velocity is 8.93 meters/second.
