Hi there,
Come on. I believe you can answer that by yourself. You just need to apply the accelerated linear motion equations and you get to your answer

Not really, but I can help you find them.
Acceleration is define as a variation of speed: [tex]a = \frac{v_1  v_0}{t}[/tex] In the case of accelerated linear motion, the average speed is equal to the mean speed: [tex]\overline{v} = \frac{v_0 + v_1}{2}[/tex] From these three equations, you have the solution to your question.
