Answer:
It take 1.78033 second get away
Explanation:
We have given that a car takes 30 m to stop when its speed is 25 m/sec
As the car stops its final speed v = 0 m/sec
Initial speed u = 25 m/sec
Distance s = 30 m
From third law of motion 
So 

Now in second case distance s = 28 m
So 

v = 6.4549 m/sec
Now from first equation of motion v=u+at
So 
t = 1.78033 sec
