Question

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

Answer 1

Velocity = (change in position)/(change in time) = (30 − 5) m / (10 − 0) s = 25/10 = 2.5 m/s. So 2.5 m/s.
