car distance

brad sue

I would like to check something.
A car leaves a city along a straight road and accelerates uniformly for 1.6 min until it reaches a speed of 120km/h. It then deccelerates uniformly until it comes to rest again after 1.6min
what is the distance traveled by the car?

I used the equ. x-x_o=.5*a*t²+v_o*t
before I found the acceleration..
I found 3.2 km

Is that right?
Thanks
