The total time is 6.45 s
The motion of the car is a uniformly accelerated motion, so we can use suvat equations.
In the first part,
(time of the first part)
So, we can find the velocity of the car after the first part, by using
This is therefore the initial velocity of the second part:
(acceleration in the second part)
So, the total time is

Glass and water are thicker and heavier than air. They are said to be 'denser' than air. What happens is that light slows down when it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction.
