Here is the problem I was given in my descriptive analytics course:

"Freshwater is in short supply in Kuwait and is therefore very expensive. One suggested remedy is to tow icebergs from Antarctica to Kuwait (a distance of about 9,600 kilometers) and melt them for freshwater. The volume of an iceberg ranges from about 500,000 cubic meters to more than 10 million cubic meters. Theoretical analysis suggests that an idealized spherical iceberg would lose about 0.2 meter of radius per day during transport, although this amount increases with the speed of towing and the distance from the pole. Fuel costs for towboats depend on the size of the boat, the speed, and the volume of the iceberg being towed. Would it be cost-effective to tow icebergs to Kuwait for freshwater, and, if so, how should this be done?"

Here is the question:

"Describe how you would seek to solve this problem. Please do not attempt to actually solve the problem."

I am having trouble figuring out how to solve the problem.
