hey dear
here is your answer
initial velocity = 0
final velocity = 30km/h = 8.3 m/s
time = 1 min. = 60 seconds
by the first equation of motion
v = u+at
8.3 = 0+60a
a = 8.3/60 = 0.138m/s²
hope it helps :)

average acceleration = change in speed / time taken.
Here change in speed = 30 kmph = 30 × [5/18] m/s
= 8.33 m/s
time taken = 1 minute = 60 seconds
hence ; average acceleration = 8.33 / 60
= 0.138 m/s²
hope this helps ..
