Problema Solution
Boat Racing The maximum speed s( in knots or nautical miles per hour) that some kinds of boats can travel can be modeled by s^2=16/9x, where x is the length of the water line in feet. Find the maximum speed of a sailboat with a 30-foot water line.
Answer provided by our tutors
Plug x = 30 into the original equation and solve:
s^2 = 16/(9*30)
s^2 = 16/270
s = sqrt(16/270)
s = 4/(3sqrt(30))
