/*  This program repeatedly reads a time in hours, computes the distance
    traveled in that time assuming a rate of 14 kilometers per hour, and
    writes the distance to the video display.  It is assumed that the 
    time is a positive integer.  The program is terminated by entering 
    zero.  The distance is computed using the formula
                      d = r * t
    where d is the distance, r is the rate, and t is the time.
