$155520$ kilometers per hour squared

Notice how:

$(1 \ "m")/("s"^2)$

$=(0.001 \ "km")/("s"^2)$

$=(0.001 \ "km")/((1/(3.6*10^3 \ "h"))^2$

$=(0.001 \ "km")/((1/(1.296*10^7 \ "h"))^2$

$=(0.001 \ "km"*1.296*10^7)/"h"^2$

$=12960 \ "km/h"^2$

So, the car's acceleration in kilometers per hour squared will be:

$12color(red)cancelcolor(black)("m/s"^2)*(12960 \ "km/h"^2)/(color(red)cancelcolor(black)("m/s"^2))=155520 \ "km/h"^2$
