Seconds() function????

// implementation file for odometer.h


Ccar::void reading(cur_speed) //distance travled will be in miles and feet
{
long dis_travled(0);
const mile(5280); // one mile = 5280 feet

dis_travled = cur_speed * 1.46;

return dis_travled
}
//this is is just the body of my function
1.46
// MPH = ---------
seconds

i got this formula off of a web site
to convert MPH to feet per sec

but how can i obtain the system seconds and incorporate
that funcion into my function?

look into time.h and the clock() function.
