acceleration=change in velocity/ time taken
change = 80km/h -60km/h= 20km/h=5.5 m/s
acceleration=(5.5 m/s) / 5s
= 1.1 ms^-2

HERE'S THE ANSWER..
__________________________
⏺️ We know
=> v = u + a × t
▶️ Where.
=> v = final velocity = 60 km / h = 16.66 m / s
=> u = initial velocity = 80 km / h = 22.22 m / s
=> t = time = 5 s
=> a = Acceleration = ?
▶️So , by putting all the values
=> a = ( v - u ) / t
=> a = ( 16.66 - 22.22 ) / 5
=> a = - 5.56 / 5 m / s^2
=> a = - 1.11 m / s^2
▶️ Here negative sign shows retardation..
HOPE HELPED..
GOOD NIGHT..
