Thanks for replying!
(Also I actually used v_f^2 = v_i^2 + 2a(x_f-x_i) oops)

But I'm confused, why is distance = velocity x time ?
Isn't in this case distance = velocity x time + acceleration affecting the velocity during the time x time?

Edit: not confused anymore, thank-you!
Edit2: actually, I'm still confused why I can use the 60.0 m/s as the only speed when speed is changing.
