Hi !
Initial velocity = u = 80 km/hr = 80*5/18 = 22.22 m/s
Final velocity = v = 60 km/hr = 60*5/18 = 16.67 m/s
Time = t = 5 sec
Acceleration = a = ?
a = v - u/t
= 16.67 - 22.22/5
= -5.55/5
= -1.11 m/s²
Acceleration of the bus is -1.11 m/s²
Initial velocity = u = 80 km/hr = 80*5/18 = 22.22 m/s
Final velocity = v = 60 km/hr = 60*5/18 = 16.67 m/s
Time = t = 5 sec
Acceleration = a = ?
a = v - u/t
= 16.67 - 22.22/5
= -5.55/5
= -1.11 m/s²
Acceleration of the bus is -1.11 m/s²

Answer:
Given, initial velocity(u)= 80km/hr= 22.22m/sec
Final velocity(v)= 60km/hr= 16.66m/sec
Time(t)=5 sec
Acceleration (a)= v-u÷t
=22.22-16.66÷5
=-1.112 m/sec
Hope it helps
