Sailboat Races The speed that a sailboat is capable of sailing is determined by three factors: its total length L, the surface area A of its sails, and its displacement V (the volume of water it displaces).
In general, a sailboat is capable of greater speed if it is longer, has a larger sail area, or displaces less water. To make sailing races fair, only boat in the same “class” can qualify to race together. For a certain race, a boat is considered to qualify if
Where L is measured in feet, A in square feet, and V in cubic feet. Use this inequality to answer the following questions.
(a) A sailboat has length
(b) A sailboat has length
