A person runs in front of you. The person accelerates uniformly from 4.0 m/s to 8.0 m/s in a time of 4.0 s.
What is the magnitude of the acceleration of the person during the 4.0 s?

The Attempt at a Solution
Vfx = Vox + at
(Vfx - Vox)/t = a
so (8m/s - 4m/s)/(4s) = a = 1.0 m/s^2
this is wrong though, so what am i failing to understand here?
