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

Then you must know that V%5B2%5D - V%5B1%5D = at,

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

So, t = %28V%5B2%5D-V%5B1%5D%29%2Fa,

and you only need to substitute numbers and calculate.

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