The total time is 6.45 s
Explanation:
The motion of the car is a uniformly accelerated motion, so we can use suvat equations.
In the first part,
(initial velocity)
(acceleration)
(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)
(final velocity)
And therefore,
So, the total time is
