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 boats in the same “class” can qualify to race together. 38A1/2 Ϫ 3V 1/3 Յ 16 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 60 ft, sail area 3400 ft2, and displacement 650 ft3. Does this boat qualify for the race? (b) A sailboat has length 65 ft and displaces 600 ft3.
