Simple Train Acceleration after elapsed time question

[rsfancy]

As a train accelerates away from a station, it reaches a speed of 4.6 m/s in 5.2 s.

If the train's acceleration remains constant, what is its speed after an additional 6.0s has elapsed?

I know I should be able to do this,but nothing I try works.If anyone could just point me the right way, I would really appreciate it. Thank You.

Well if you have the change in speed and change in time, then what is the acceleration? Then once you have that, you can plug that into:

v = v_0 + at

Thanks a lot, I really appreciate the help. I was going insane, but I realize I skipped the fact that I needed to find the acceleration first.

I won't make that mistake again. Once again thanks for the help!
