Answer :
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.
