Answer:
Neither; see below
Step-by-step explanation:
Your acceleration: [tex]a=\frac{\Delta v}{\Delta t}=\frac{25-0}{25}=1m/s^2[/tex]
Your friend's acceleration: [tex]a=\frac{\Delta v}{\Delta t}=\frac{6-0}{6}=1m/s^2[/tex]
Therefore, since both you and your friend accelerate at the same rate, neither is faster.
