Help with an Average Acceleration question during a time period

[honey.s]

If a rugby player is running at 3.69 m/s and then decides to sprint in a straight line for a ball and 3.27 seconds later is running at 7.29 m/s, what is their average acceleration during that time? Units and direction of travel are not required

Homework Equations

The Attempt at a Solution

I've used Avg Acceleration = v2-v1 / t2-t1 ... 7.29-3.69/3.27
Final answer = 1.1

Your answer is right.
Do you have any reason to think it is wrong?
