• 3. The time to deliver a load was indirectly proportional to the quarts 

 sold per mile. 



4. The miles traveled to deliver a load were indirectly proportional to the 

 quarts sold per hour. 



5. The miles traveled to deliver a load were directly proportional to the 

 time required to deliver the load. 



6. The quarts sold per mile were indirectly proportional to the quarts 

 sold per hour. 



These different operations have been figured out for the different cities 

 studied with the following results. 



Table No. V shows that there is very little relation between the miles 

 traveled to deliver the load and the quarts sold per hour of the_ different 

 dealers in the three cities named. This is accounted for, first, by the per- 

 sonal element met with in the driver, as each driver is of different abihty to 

 deliver milk. Second, the kind of vehicle, as an automobile or auto truck is 

 able to cover more territory and give more time for the deliveryman to de- 

 liver his milk. Third, the character of territory with regard to kind of roads, 

 accessibilit}^ of customer, etc., affects the miles traveled and time of dehvery.
