Budget: $15
The cost of fuel to propel a boat through the water (in dollars per hour) is proportional to the cube of the speed. A certain ferry boat uses $100 worth of fuel per hour when cruising at 10 miles per hour. Apart from fuel, the cost of running this ferry (labor maintenance, and so on) is $675 per hour. At what speed should it travel so as to minimize the cost per mile traveled?The cost of fuel to propel a boat through the water (in dollars per hour) is proportional to the cube of the speed.
