If the brisk walk were done at 4.0mi/h how far would the student have to walk to burn pound of fat
To determine the distance the student would have to walk to burn one pound of fat at a brisk walk of 4.0 miles per hour, we need to understand the relationship between calories burned and weight loss.
1. Calories and weight loss: One pound of body weight is approximately equivalent to 3,500 calories. This means that to lose one pound of fat, you need to burn around 3,500 calories.
2. Determining calories burned: The number of calories burned during physical activity depends on factors like body weight, intensity of exercise, and duration. To estimate the calories burned during walking, we can use the MET (Metabolic Equivalent of Task) value. The MET value represents the energy expenditure of an activity relative to resting (which is typically set at 1 MET). Walking at a brisk pace of 4.0 miles per hour has a MET value of around 4.5.
3. Calculating distance: We can use the following formula to estimate the distance required to burn one pound of fat:
Distance (in miles) = (Calories Burned / (Body Weight in pounds * Calories per Mile))
4. Plugging in the values:
Let's assume the student weighs 150 pounds.
Calories burned to lose one pound = 3,500
Calories per mile at 4.0 mi/h: This value can vary depending on factors such as weight, fitness level, and efficiency. As a rough estimate, we can use an average of 100 calories per mile.
Distance (in miles) = (3,500 / (150 * 100))
5. Calculating the distance: Plugging in the values into the formula, we get:
Distance (in miles) = 0.0233 miles
Therefore, the student would need to walk approximately 0.0233 miles (or 120 feet) at a brisk pace of 4.0 miles per hour to burn one pound of fat.
