Thank you for asking this question.
To find the acceleration we must know the initial velocity, final velocity and the total time taken.
As the formula for acceleration is a= v-u/t where v is the final velocity, u is the initial velocity and t is the time taken.
Now we can calculate deceleration. a = (v - u)/t so (60-80)/5 = -4m/s^2. So acceleration comes out to be -4 m/s^2.
