I do not know where to start

You should start by listing the given information.
vi = 0
vf = 100 m/s
t = 12.5s
a = (vf-vi)/t
A). a = (100m/s - 0m/s)/12.5 s
a = 8.00 m/s^2
B). You can use several equations for this question. I'm going to use: d = (vf + vi)/2 * t.
d= (100m/s + 0m/s)/2 * 12.5 s
d= 625m
C). Vave = d/t
Vave = (625m/12.5s)
Vave = 50 m/s
I do realize that this answer is 4 years late! :D, but maybe it'll help someone else.
