Since you use the terms from Physics, I assume that you know the beginnings of Physics.

Then you must know that - = at,

where the difference on the left side is the increment of velocity, "a" is acceleration and "t" is time.

So, t = ,

and you only need to substitute numbers and calculate.

O, yes, before making calculations, you must convert km/h to m/s.
