walking at a brisk pace burns off about 280 Cal/h. How long would you have walk to burn off the Calories obtained from eating a candy bar that contained 3 g of protein 12 g of fat, and 28 g of carbohydrates

Sagot :

Calories are said to be the amount of energy a particular food can produce or give when it is consumed.

It will take almost 50 minutes of walking at a brisk pace to burn off the calories obtained from eating a candy bar.

It is important to note that:

1 gram of carbohydrate = 4 calories

1 gram of protein = 4 calories

1 gram of fat = 9 calories

The total number of calories in a candy bar is calculated as:

  • Number of grams of protein in the candy bar = 3g

Hence, the number of calories of protein =

1 g of protein = 4 calories

3 g of protein = ?

Cross multiply

3g x 4 calories / 1 g

= 12 calories.

  • Number of grams of fat in the candy bar = 12g

Hence, the number of calories of fat =

1 g of fat = 9 calories

12 g of fat = ?

Cross multiply

12 g x 9 calories / 1 g

= 108 calories.

  • Number of grams of carbohydrates in the candy bar = 28g

Hence, the number of calories of carbohydrates =

1 g of carbohydrates = 4 calories

28 g of protein = ?

Cross multiply

28g x 4 calories / 1 g

= 112 calories.

The total number of calories in the candy bar = 12g + 108g + 112g

= 232 calories,

From the question, a brisk pace burns off 280 cal/h. Hence, this means:

280 calories = 1 hour

232 calories = ?

Cross Multiply

232 calories x 1 hour / 280 calories

= 0.83 hour

Converting 0.83 hour to minutes

1 hour = 60 minutes

0.83 hour = ?

Cross multiply

0.83 hour x 60 minutes

= 49.8 minutes

Therefore, approximately it will take almost 50 minutes of walking at a brisk pace to burn off the calories obtained from eating a candy bar.
