The chart shows Daniela’s run through her race.
A graph with horizontal axis time (seconds) and vertical axis position in (meters). The line runs straight from 0 seconds 5 meters to 10 seconds 30 meters.
What is her velocity?
1.5 m/s
2 m/s
2.5 m/s
5 m/s
To find Daniela's velocity, we can use the formula:
Velocity = Change in distance/Change in time
The change in distance is 30 meters - 5 meters = 25 meters.
The change in time is 10 seconds - 0 seconds = 10 seconds.
So, the velocity is:
Velocity = 25 meters/10 seconds = 2.5 m/s.
Therefore, her velocity is 2.5 m/s.
