Acceleration Logic is this right?

Homework Statement

A speed skater moving across frictionless ice at 8m/s hits a 5m patch of ice. She slows steadily then continues at 6m/s. What is her acceleration on the rough ice?

Homework Equations

Not sure

The Attempt at a Solution

6m/s - 8m/s = -2m/s * 1/5m = 1/10 s

-2m/s * 1/10s = -1/5m/s^2

I'm not sure if my logic follows through

I don't understand what you are trying to do. If you're trying to find the time it takes to traverse that 5m patch, consider the average speed of the skater during that time. Then you can use Distance = ave speed * time to find the time.
