With the given:
x(m): 0 3.7 8.2 22.8
t(s): 0 1.0 2.0 3.0
How would you calculate the average velocity?

Well, the average velocity is the total distance covered divided by the total time it took to cover that distance.
In your case, after 3.0 seconds, 22.8 meters of distance were covered. 22.8 m/ 3.0 s = 7.6 m/s.
Note that much of the info in the problem you don't actually need, but it might be there for other problems nearby. Hope that helps! :)

what u could also do is determine the average distance between each point
3.7 -0 / (1-0)
8.2 - 3.7 / (2-1)
etc...
and sum your results and divide by 3 (in this case), it should come up very close 2 just 22.8/3....

Just take the whole distance so
delta x = final - initial distance = 22.8 -0 =22.8
delta t = final -initial time = 3.0 - 0 = 3.0
avg. velocity = 22.8/3.0 = 7.6 m/s
This is different from the instantaneous velocity in which you would plot the distance vs. time and then take the slope of the tangent at a certain time.

Total distance covered/ total time spent = avg SPEED. Velocity implies a vector direction...
(22.8 - 0)/(3.0-0) = (solve...)

The total distance travelled divided by the time it took. That is your average velocity,
