/*   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.
