Hello ashurina. Welcome to PF !

What have you tried?

Where are you stuck?

According to the rules for Homework Help on this Forum, you need to show effort before we can help you.
 
I have tried t = v1-v2/ a however, I am stuck because it gave me a rather large number like 206 it doesn't seem logical. And thank you, I didnt realize that
 
You're equating v1=669 m.
Unit for velocity v is m/sec.
 
This is a very easy problem.
use s=ut+(1/2)at[itex]^{2}[/itex]
 
Shouldn't give the PO the solution.
