Pretty simple distance traveled given acceleration problem

[BC2210]

Homework Statement

Hey, I am not sure why I can't get the right answer for my online physics homework, it keeps telling me the answer I am putting is wrong! My question is:

The light turns green, and a bicyclist starts forward with an acceleration of 1.0 m/s^2. How far must she travel to reach a speed of 7.8 m/s?

I think I am going about figuring it out the wrong way...

Thanks for any help! :)
