You are loading 475,000 barrels of cargo oil. At 0800 on 8 July, you find that you have loaded 174,000 barrels. At 1000, you find that you have loaded 192,000 barrels. If you continue loading at the same rate, you will finish at approximately __________.
• Loading rate (barrels per hour) between two time checks • Using the basic speed formula rearranged for time: ( \text{Time} = \frac{\text{Distance}}{\text{Speed}} ) — here "distance" is barrels remaining • Converting fractional hours into hours and minutes
• From 0800 to 1000, how many hours passed, and how many barrels were loaded in that period? What is the loading rate in barrels per hour? • How many barrels are left to load after 1000? At the rate you just calculated, how many hours will it take to load the remaining cargo? • When you add that number of hours to 1000 on 8 July, what clock time (including minutes) do you get, and which choice is closest?
• Be sure your time interval between 0800 and 1000 is in hours, not minutes. • Check that you subtract correctly to get barrels remaining after 1000. • Convert the decimal part of your hours to minutes by multiplying by 60 before matching to the nearest choice.
