Your numbers require dimensions. That is one of the first things a physics class should teach you.
One way of stating the problem correctly would be:
A skater is gliding along the ice at 2.2 m/s, when she undergoes an acceleration of magnitude 1.2 m/s^2 for 3.0 seconds. At the end of that time she is moving at 5.8 m/s.
That would be a statement of fact and not a question. They already provide the correct final velocity.
