If the pitch of the propeller is 26.7 feet, and the revolutions per day are 131,717, calculate the day's run allowing 4% negative slip.

Correct Answer: Option A — 601.6 miles

Calculate theoretical distance by multiplying propeller pitch (26.7 ft) by revolutions per day (131,717), dividing by feet per nautical mile (6076.1). Apply 4% negative slip (multiply by 0.96) to determine the true day's run of 601.6 miles.
