A truck traveling at a constant speed of 40.0 km/h applies its brakes and comes to a complete stop in 5.0 s. The truck starts again and accelerates at a constant rate of 0.80 m/s2. After restarting, how far does the truck travel before reaching its original speed of 40.0 km/h?

I am not certain what How far means? The total distance, or just the distance accelearting?
If the distance accelerating
Vf^2=2ad
change km/hr to m/s, solve for d.
