How To Calculate Time To Finish Loading Cargo

You are in the process of loading 465,000 barrels of cargo oil. At 1030, on 5 November, you gauge the vessel and find that you have loaded 203,000 barrels. At 1200, you find that you have loaded 219,000 barrels. If you continue loading at the same rate, you will finish at approximately:

Given:
465,000 bbls- Total cargo to load.
203,000 bbls- Cargo loaded at 1030H 5 November
219,000 bbls- Cargo loaded at 1200H 5 November

What is asked:
Time to finish loading the remaining cargo.

Solution:

Step 1. Get the difference of time and cargo loaded from 1030H to 1200H.
               1200H - 1030H = 1.5 hrs
              219,000 bbls - 203,000 bbls = 16,000 bbls
           
 * We have loaded 16,000 barrels in 1.5 hrs.

Step 2. Solving for the rate of loading.
              16,000 bbls ÷ 1.5 hr = 10,666.67 bbls/hr

Step 3. We have to solve for the remaining cargo to load.
              465,000  bbls - 219,000 bbls = 246,000 bbls

Step 4. Solving for how many hours to load the remaining cargo.
             246,000 barrels ÷ 10,666.67 barrel/hr = 23.06 hrs

Step 5. Solving for the time to finish loading the remaining cargo.
         ***23.06 hrs is equal to 2304H

             1200H   5   November
          + 2304H_____________
            3504H  5  November
          - 24 hr + 1 day________
           1104H  6 November is the final answer.
