Answer :
Final answer:
The yacht Henrietta's average speed in the Great Ocean Yacht Race was approximately 8.98 nautical miles per hour.
Explanation:
The yacht Henrietta won the Great Ocean Yacht Race in 1866, traveling a distance of approximately 3000 nautical miles. The winning time was 13 days and 22 hours, to the nearest hour. To find the yacht's average speed in nautical miles per hour, we can divide the distance by the time it took to travel it.
Converting the winning time to hours, we have
13 days = 13 x 24 = 312 hours and 22 hours = 22 hours. Therefore, the total winning time is.
312 + 22 = 334 hours.
Dividing the distance of 3000 nautical miles by the total winning time of 334 hours, the yacht's average speed is approximately 8.98 nautical miles per hour.
