Question

The calorie cost of cycling can be estimated using the formula: Calories Burned = (METs * 3.5 * weight in kg) / 200 * duration in hours. For biking at a moderate effort (12-13.9 mph), the MET value is approximately 8. However, since Jessica is biking at 17 mph, we'll use a MET value closer to vigorous cycling, which is around 10. First, convert her weight to kilograms (1 lb = 0.453592 kg), so 125 lbs is approximately 56.7 kg. Next, convert the duration from minutes to hours, so 25 minutes is 25/60 = 0.4167 hours. Plugging these values into the formula gives: Calories Burned = (10 * 3.5 * 56.7) / 200 * 0.4167 ≈ 178 calories.
