Question:

If during a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25 s. What is the sprinter's average acceleration during this period?

Answer:

Acceleration is the rate of change of velocity over time. So 7.5 divided by 5.0, find your quotient then divide that number by 1.25 seconds.
