Hey there!
=>> You should first mention the time taken by the car to accelerate. Then use the following formula:
20 km/h = (1000/3600) * 20 m/s= 5.55 m/s; 60km/h =(1000/3600)* 60 m/s = 16. 67 m/s
a= v-u/t = 16.67-5.55/t =(11.11/t)m/s2
Hope it helped!!!!!☺️

initial velocity=20km/hr so in m/s it will be 100/18 m/s final velocity =60
300/18 m/s
time =6 sec
so acceleration =v-u/ t
300/18-200/18/6=200/18×6
so a=1.85 m/s^2
300/18 m/s
time =6 sec
so acceleration =v-u/ t
300/18-200/18/6=200/18×6
so a=1.85 m/s^2
