1. An average fuel consumption rate measuring system comprising:

  • a distance measuring circuit for generating a first electric signal each time a predetermined distance is traveled by a running vehicle;

    a distance integrating circuit connected to said distance measuring circuit for counting said first electric signals to form an integrated value indicative of the cumulative distance traveled by said vehicle;

    a fuel measuring circuit for generating a second electric signal each time a predetermined quantity of fuel is consumed by said vehicle;

    a fuel integrating circuit connected to said fuel measuring circuit for counting said second electric signals to form an integrated value indicative of the cumulative amount of fuel consumed by said vehicle;

    a divider circuit connected to said distance integrating circuit and said fuel integrating circuit for repetitively obtaining an average fuel consumption rate by dividing the integrated cumulative value of one of said integrating circuits by that of the other of said integrating circuits each time a selected one of the integrated cumulative values increases by a predetermined value; and

    an indication circuit connected to said divider circuit to indicate the result of said division by said divider circuit.
