A typical \(68\text{-kg}\) person generates a steady mechanical power output of \(120\text{ W}\) at the pedals of a bicycle. Approximately how many Calories are “burned” (total metabolic energy expended) when the person rides a bicycle for \(15\text{ minutes}\)? A typical energy efficiency for the human body is \(25\%\), which takes into account the release of thermal energy. Note (\(1\text{ Cal} = 4186\text{ J}\)).
