The task involves understanding the concept of work rate, which is determined by the amount of work completed over time. If the first painter can complete the entire job in twelve hours, we need to determine how much of the job he accomplishes in one hour.

To find the work rate, we take the total job (which can be considered as 1 whole job) and divide it by the total time it takes to complete it. Therefore, if the painter completes 1 job in 12 hours, his work rate can be calculated as follows:

1 job ÷ 12 hours = 1/12 of the job per hour.

This means that every hour, the painter completes one-twelfth of the total job. Understanding this relationship between total work and time allows us to determine the rate of work done in a systematic way. Hence, the rate of 1/12 of the job per hour accurately reflects the painter's work efficiency based on the total time required to complete the job.
