🔍 Key Concepts

• Propeller pitch and revolutions to get theoretical distance traveled • Effect of negative slip on the actual distance run (+ vs – adjustment) • Converting feet of travel into nautical miles or miles using the correct divisor

💭 Think About

• First, ignore slip and compute how many feet the ship would travel in one day if it moved exactly one pitch length for every revolution. What is the formula? • Next, decide how negative slip changes that theoretical distance: does 7% negative slip mean you multiply by (1 – 0.07) or (1 + 0.07)? • Finally, convert your answer in feet to miles. Which length in feet should you divide by for this type of navigation problem, 5,280 or about 6,080?

✅ Before You Answer

• Be sure you are using revolutions per day, not per hour, in your calculation. • Confirm that you have applied the 7% to the total theoretical distance, not just to pitch or revolutions separately. • Double‑check that you are dividing by the correct number of feet per nautical mile or statute mile before comparing to the choices.
