Why do you need to know the deceleration constant if we are talking about the car accelerating and going to 55 mi/hr?

I would assume you just plug it into the constant acceleration formula and that is it.

I was also thinking maybe it has to accelerate to first at a constant rate and then decelerate to slow to 55 mph. I which case I have no idea how to solve the problem.

Anyone wanna take a stab at this?
