**MathMate**, Wednesday, September 1, 2010 at 2:53pmIt is mainly a matter of units conversion.

Decide on what units you'd like to use for the final answer (usually seconds for cars). Convert everything to metres and seconds and use

time = (final velocity - initial velocity) / acceleration

To change from mph to m/s

multiply by

63360*0.0254/3600

=0.44704

I get 12.4 seconds
