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.
