    Given a list of delivery route distances containing both precise GPS measurements and checkpoint estimates in kilometers, create a function that rounds each distance to the nearest kilometer and returns the sum of all rounded distances multiplied by the total number of route segments. This calculation helps determine the total fleet distance coverage while accounting for measurement variations across different tracking systems.
