To find the total energy content of the meal, calculate the energy from each macronutrient:  - Fat: 58.0 g × 38 kJ/g = 2204 kJ  - Protein: 39.0 g × 17 kJ/g = 663 kJ  - Carbohydrate: 177 g × 17 kJ/g = 3009 kJ  Total energy = 2204 + 663 + 3009 = 5876 kJ  To find the time to burn off 5876 kJ by jogging at 950 kJ/hour:  5876 kJ ÷ 950 kJ/hour = 6.18 hours  Convert hours to minutes: 6.18 hours × 60 minutes/hour = 371 minutes.
