average driving velocity !!!

Hi people,

am working under Simulink and want to calculate average driving velocity.

I have lookup table who´s look like:

 time (s)            0  10  20  30  40  50  60  70  80 85
 Velocity (km/h)     0  45  55  20   0   0  30  25   0  0

I need embedded function ( or better a bloc ) to estimate the " time where the velocity is different to zero" along the whole driving cycle

On this step of my simulation i just need a ( embedded ) function or bloc to calcute the deplacement time...

 T(deplacement time) = T (time overall the cycle) - T ( V = 0 km/h )

Distance is the Integrale of the velocity over the time ( that´s not a problem )

           => V(average) = Distance / T(deplacement)

Thanks
