Final answer:
Without specific data about the barge's capacity and the oil usage rate, an accurate calculation of the oil supply in minutes cannot be provided. Please provide the necessary information to proceed with the calculation.
Step-by-step explanation:
The question you have asked about the oil supply contained in a barge from the Richmond plant is related to Mathematics, as it involves calculations of volume, rate of use, and time.
However, in order to provide an accurate answer, specific data about the capacity of the barge and the usage rate of the oil is required.
Without this information, it is not possible to calculate the number of minutes the oil supply would last.
If you can provide the capacity of the barge in barrels or gallons, and the rate at which the oil is consumed (for example, in barrels per day), we can then use those figures to calculate the total number of minutes the supply would last.
