The power P required to propel a ship varies directly as the cube of the speed s of the ship. If 6500 hp will propel a ship at 13.0 mi/h, what power is required to propel it at 16.0 mi/h? Set up the general variation equation. P= (Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) The power required to propel the ship at 16.0 mi/h is (Round to the nearest hundred as needed.) hp.
