Sailboat speed.

[kelly1]

Another word problem. Any help is greatly appreciated!!

The sail-displacement ratio S provides a measure of the sail power available to drive a boat. For a boat with a displacement of d pounds and a sail area of A square feet: S=16Ad^-2/3, find S to the nearest tenth for the Tartan 4100 which has a sail area of 810 square feet and a displacement of 23,245 pounds. and solve the formula for d. Thanks!!
