Assuming that ten people plan to trek 500 miles to the North

Assuming that ten people plan to trek 500 miles to the North pole, outline the steps you would take to calculate the amount of food they should pack, taking into account the number of sled dogs needed and the food needed for the dogs. Suppose you use a tire pump to inflate a tire on a bicycle the selected pressure created in the tire represents a form of potential can do mechanical the tire making. The potential energy in derived from chemical-bond energy in your food. Trace the energy from your mouth at a meal unit it ends up in the tire, identifying losses of as heat along the way.

Solution

First we have to find out the time the trek will take. Assuming the entire distance is to be covered using dogs, which can travel upto 40 miles a day, the entire journey will take 25 days. Assuming we have 10 sleds, with four dogs each, we will have 40 dogs and 10 people to feed for 25 days. The calorific requirements will also be high due to lower temprature and physical exertion. So we end up with the need for highly calorific food for 10 people and 40 dogs for 25 days with lots of carbohydrates, fats and protein and occasionally food with more balanced nutrients along the way to prevent the severe lack of any kind of nutrient.
