Initial velocity of the bus = 80 km/h = 22.22 m/s
The final velocity of the bus = 50 km/h = 13.88 m/s
Time is taken by the bus = 4 s
Acceleration of the bus = (Final velocity - Initial velocity)/time
= (13.88 - 22.22)/4
= - 8.34/4
= - 2.085
Acceleration of the bus is - 2.085 m/s²
Hope this helps you.

no it's wrong , the speeds are given in km/ hr
first u need to change it to m/s
whole solution is wrong
thanks
@ kiki9876 has given the correct answer
sry I forgot to change
ok
