Question 164708: The maximum hull speed, S, is directly proportional to the square root of the length of the water line, L, on a sailboat. A boat with an L of 16.5 feet can go 5.4 knots.
What is the variation constant?
This is the formula we came up with: 5.4=k(square root of 16.5)
We could not get any further. Thanks

The maximum hull speed, S, is directly proportional to the square root of the length of the water line, L, on a sailboat. A boat with an L of 16.5 feet can go 5.4 knots.
What is the variation constant?
:
That's the equation you have, just solve for k:
*k = 5.4
:
Square both sides
16.5*k^2 = 5.4^2
:
16.5*k^2 = 29.16
k^2 =
k^2 = 1.7673
k =
k = 1.33 is the variation constant
:
:
The formula for this design: S = 1.33
;
Check our solution. let L = 16.5
S = 1.33
S = 1.33 * 4.06
S = 5.3998 ~ 5.4
