If the pitch of the propeller is 22.4 feet, and the revolutions per day are 103,690, calculate the day's run allowing 9% positive slip.

Correct Answer: Option B — 347.6 miles

Theoretical distance is the product of pitch (22.4') and total revolutions (103,690), equaling 2,322,656 feet. Converting to nautical miles (divide by 6,076.1) gives 382.26 miles. Applying 9% positive slip (multiply by 0.91) results in 347.8 miles, which aligns with the provided answer of 347.6 miles.
