How to find an average acceleration using an average velocity?

Cacti

Homework Statement
Calculate the average acceleration for each member over the first 10.0 m.
Homework Equations
None given
I calculated the average velocity in a previous problem and got 1.146788991m/s over a time of 8.72s. I know I can’t use a_ave=(Vf-Vi)/(Tf-Ti) because I don’t know the final velocity and have no way to find it. Do I multiply average velocity by time?

The full problem statement is necessary. For one thing, there is a difference between "average" over time versus "average" over distance.

Not if you are looking for something that has dimensions of acceleration.

Maybe average velocity= (Vf - Vi)/2?

The rule of the HW forum is that you post the full statement of the problem, not just snippets of it.
