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*t

^{2}+v

_{o}*t

before I found the acceleration..

I found 3.2 km

Is that right?

Thanks
