Question 1073315: Sailors traditionally measure speed in knots, or nautical miles per hour. A nautical mile is based on the circumference of the earth, and 1 nautical mile=1.15 mile. If a ship is traveling at 15 nautical miles per hour, how fast is it going in miles per hour? What about in feet per second?

You can put this solution on YOUR website! Sailors traditionally measure speed in knots, or nautical miles per hour. A nautical mile is based on the circumference of the earth, and 1 nautical mile=1.15 mile. If a ship is traveling at 15 nautical miles per hour, how fast is it going in miles per hour? What about in feet per second?
=================================================
a) 15 nauts/hr * 1.15mi/naut = 17.25 mi/hr
b) 17.25 mi/hr * 5280 ft/mi * (1hr/3600s) = 25.3 ft/sec
