Question 1 of 27070

🔍 Key Concepts

• Look at the river mileage on the inland river charts for the Mississippi River between Cairo Point Light and Memphis • Understand how mile markers (river miles) are measured along the Mississippi River (increasing or decreasing in which direction) • Use the description of the Lion Oil Refining Co. Docks in the Light List or river tables to find its exact river mile

💭 Think About

• First, determine the river mile at Cairo Point Light. What reference (Upper/Lower Mississippi) and mile number is used there? • Next, find the listed river mile for the Lion Oil Refining Co. Docks in Memphis. How is it described in the reference tables? • Once you have both river miles, how do you use simple subtraction to find the distance you must travel downstream?

✅ Before You Answer

• Confirm the correct river segment (Mississippi River – not Ohio River or other tributaries) • Verify both features (Cairo Point Light and Lion Oil Refining Co. Docks) are read from the same mileage system and direction • After subtracting, make sure your result matches one of the choices and is a reasonable run for a line-haul towboat trip to Memphis
