How many calories will 150 pound person burn if he or she walks to 2 mph for one hour?
A person who weighs 150 pounds will burn approximately 204 calories by walking at 2 mph for one hour.
To estimate the number of calories burned while walking, we can use a commonly used formula called the MET (Metabolic Equivalent of Task) value. The MET value is a measure of the energy cost of an activity compared to resting metabolism.
For walking at 2 mph, the MET value is around 2.9. If we assume a person's weight is 150 pounds, we can use the following formula to estimate the calories burned:
Calories Burned = MET value x weight (in kg) x time (in hours)
First, let's convert the weight from pounds to kilograms. Since 1 pound is approximately 0.45 kilograms:
Weight in kg = 150 pounds x 0.45 kg/pound = 67.5 kg
Next, let's calculate the calories burned:
Calories Burned = 2.9 x 67.5 kg x 1 hour = 196.65 calories
Therefore, a 150-pound person walking at 2 mph for one hour will burn approximately 196.65 calories.
To calculate the number of calories burned during a walking activity, we can use the following steps:
1. Determine the metabolic equivalent (MET) value for the activity: The MET value represents the energy expenditure of an activity compared to the energy used while at rest. The MET value for walking depends on the speed and intensity of the activity. In this case, walking at 2 mph corresponds to a MET value of 2.9.
2. Calculate the total energy expenditure (TEE): The TEE is determined by multiplying the MET value by the individual's weight in kilograms and the duration of the activity in hours.
Let's break down the calculation:
First, convert the weight from pounds to kilograms:
150 pounds = 68.04 kilograms (rounded to two decimal places)
Next, to calculate the TEE:
TEE = MET value × weight in kilograms × duration in hours
TEE = 2.9 × 68.04 kg × 1 hour
Now, let's calculate the answer:
TEE = 198.036
Therefore, a 150-pound person would burn approximately 198 calories by walking at 2 mph for one hour.
