Initial velocity of car(u) = 20 km/hr
= 20 × 5/18 m/s
= 50/9 m/s

Final velocity of car(v) = 60 km/h
= 60 × 5/18 m/s
= 50/3 m/s

Time taken(t) = 6 seconds

As, we know formula for acceleration is -

(v-u)/t

= {(50/3 ) - (50/9)} / 6

= {(150-50)/9} /6

= 100/9 /6

= 100/54

= 1.851 m/s

Answer) Acceleration is 1.851 m/s.
