Alexander, who weighs 159 , decides to climb Mt. Krumpett, which is 5460 high. For his food supply, he decides to take nutrition bars. The label on the bars states that each 100- bar contains 10 of fat, 40 of protein, and 50 of carbohydrates.Alexander wants to know exactly how many bars to pack in his backpack for the journey. To provide a margin of safety, he assumes that he will need as much energy for the return trip as for the uphill climb. How many bars should Alexander pack?

Question

How would I even go about solving this problem? The total calories is 450 for a total bar that I calculated, is this right?

Answer 1

Is this what they call chemistry nowadays?

How times have changed.

Is Alexander's weight in pounds? Is the moutain's height in feet?

You can compute the calorie content of the bar, but somwhere you will need an estimate of how much food energy he needs to climb the mountain and come down. It will exceed the work done, which will be less when coming down. They need to provide you with additional information. Food energy cannot be converted to work with 100% efficiency.
