Calculating Deceleration and Stopping Time for Margo's Corvette

[almost__overnow]

Margo's Corvette brakes from 32 m/s to 8.0m/s in 6.0 seconds. What is the average deceleration?

If the car continued decelerating at this rate, how long would it take to stop?

i just need to know how to do it cause my answers never came out right.
