The speed of a car traveling on a straight road increases from 63 m/s to 75 m/s in 4.2 s what is the cars acceleration ?

Please help

acceleration = rate of change of velocity or the slope of the velocity curve
a = (V2-V1)/ (T2-T1)
here:
a = (75 - 63) / (4.2 - 0)
a = (12 / 4.2) meters/ second^2
..... and it is Physics :)

I am not a mind reader.
I am good at science but not math mixed with science. lol.
