One of the first scales to estimate wind speeds and the effects was created by Britain's Admiral Sir Francis Beaufort (1774- 1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations. The scale starts with 0 and goes to a force of 12. The Beaufort numbers B, can be modeled by B = 1.69√8 +4.45 3.49 where s is the speed of the wind in miles-per- hour. Find the wind speed that corresponds to the Beaufort number B = 11. Round your solution to the nearest whole number.
