Question

Boat builders share an old rule of thumb for sailboats. The maximum speed 𝐾 in
knots is 1.35 times the square root of the length 𝐿 in feet of the boat’s waterline. If a customer is planning
on ordering a sailboat with a maximum speed of 8 knots how long should the waterline be? How much
longer would the waterline have to be to achieve a maximum speed of 10 knots?
