If I am given the acceleration of 4 m/s(sqaured) and a total time of 12 m/s what formula would i use to find the average velocity?

Erm... 12 m/s is not a time. Anyway, average velocity is . See e.g. wiki.
Apparently you need a couple of assumptions. Initial speed of zero and acceleration until 12 m/s or something like that. With assumptions like that you could calculate and .

Here is the question: An airplane maintains a constant acceleration of 4 m/ssquared E as it speeds up from 16m/s t0 to 28 m/s E what is the av. velocity?

Ah well, in that case you can simply take the average of the initial and the final speed. Alternatively, you can calculate and . But you'll get the same result.
thank you, much appreciated. Im new and some info needs to be sorted >.<!
