help with physics, velocity ...?

i am taking physics gr 11 and i need an answer to that question ASAP plz....

this question is about this rocket..here is a picture of my graph..plz help!

the complete question is

compare the instantenous velocities that you calculated for times 7 s , 13 s , 21 s , and 25 s. with the average velocities for the intervals that inclused those times In which case is the instantaneous and average velocities nearly the same? quite different? explain why..

here is the picture of the graph http://123pichosting.com/viewer.php...

Update:

i did try!! LOL i jsut dont get it..some one plz tell me at least how to do it

    So i'll merely permit you recognize the physique of suggestions to fixing it : First you will possibly desire to calculate the whole displacement travelled, via multiplying the speed to time then you might desire to sum up the whole time (upload at the same time) finally, v = s/t = displacement / time So divide the whole displacement you acquire with the whole time you acquire this is uncomplicated speed P.S. do no longer forget approximately that speed is a vector, so which you will possibly desire to provide the guidelines !
