Gary is planning a 3-day backpacking trip and decides to hike an average of 4 h each day. Hiking requires an extra 330 Calories per hour. How many pounds will Gary lose during the trip if he consumes an extra 900 Calories each day? (3500 Calories are equivalent to 1 lb.)

Question

Quizplus · Accepted Answer

Total hiking time for the trip = 3 days * 4 hours/day = 12 hours
Total calories burned during the trip = 12 hours * 330 Calories/hour = 3,960 Calories

Total calories consumed during the trip = 900 Calories * 3 days = 2,700 Calories

Net calories burned during the trip = 3,960 Calories - 2,700 Calories = 1,260 Calories

Number of pounds lost = Net calories burned / 3500 Calories per pound = 1,260 Calories / 3500 Calories per pound = 0.36 pounds ≈ 0.4 pounds

Therefore, Gary will lose around 0.4 pounds during the trip. The best choice is C.
