Explanation / Answer

Calorific value of Carbohydrate = 4 Cal/g

Calorific value of fat = 9 Cal/g

Calorific value of protein = 4 Cal/g

Amount of calories from 46 g carbohydrate=46x4=184 Cal

Amount of calories from 45 g fat = 45 x 9 = 405 Cal

Amount of calories from 52 g protein = 52 x 4 = 208 Cal

Total energy = 184 + 405 + 208 = 797 Cal.

Time required to burn all the calories = 797/11 = 72.45 minutes
