How many calories in a doughnut?
There are over 200 calories in a glazed
doughnut.
Chocolate doughnut
Did you know that one chocolate doughnut has
over 250 calories, and a glazed chocolate
doughnut has 300 calories.
Number of calories burned depends on what
In sports shops there are stuff that you put on
your hand or legs to see how many calories you
are burning while running.
The amount of calories that running burns per
kilometer varies from person to person
depending on factors such as :
Weight , running speed , duration of running
and whether you are a girl or a boy.
The most important factor is weight
To find out how many calories burned
when running
Multiply your weight in kilograms by how many
kilometers you ran and 1.036
Calories burned = weight (kg) × Km × 1.036
A person who weighs 52.3 kg and
runs 1 km would burn :
Calories burned = weight (kg) × km × 1.036
Calories burned = 52.3 × 1 × 1,036
= 54.1828 calories per 1 km
How far would that person have
to run to burn the calories that
are in a doughnut ?
If he ate a glazed doughnut which has 200 calories ,
he needs to run for about 3.7 km .
Calories = kg × km × 1.036
= 52.3 × ? × 1.036 = 200
First we multiply 52.3 × 1.036 = 54.1828
Then we divide 200 by 54.1828
200 ÷ 54.1828 = 3.69 km
Who do you think needs to run more
to burn calories from a doughnut
Let’s compare between two boys, the first boy’s
weight is 40 kg while the second boy is 70kg
Using the formula : weight × km × 1.036
First boy : 40 × 1 × 1.036 = 41.44 calories
Then we divided 200 by 41.44
200 ÷ 41.44 = 4.8 km
Second boy : 70 × 1 × 1.036 = 72.52 calories
200 divided by 72.52
200 ÷ 72.52 = 2.7 km
Have you ever wondered how many
calories in French Fries !!!
medium portion of French fries has 360 calories.
So if you weight 52.3 kg and you want to know how
many calories you burn when running
Calories = weight (kg) × km × 1.036
= 52.3 × ? × 1.036 = 360
(52.3 × 1.036 = 54.1828 )
54.1828 × ? = 360 so I can get the answer by
dividing 360 by 54.1828 =
360 ÷ 54.1828 = 6.64 km
So if you decided to eat medium French fries rather than a glazed
doughnut you would have to run 2.95 kilometers more
Km you run to burn French Fries subtract Km you run for doughnut
6.64 – 3.69 = 2.95 km
Knowing arithmetic with decimals help me
make good decisions by :
Calculating calories by adding up all the food that you
have eaten in one day for an example.
Trying to avoid food that have big calories, and even
decimals add up together not only whole numbers
Doing activities that burn more calories.
Using the required formula to find out how many
calories burned from each activity you do
Arithmetic with decimals help me
develop these parts of the Learner
Profile
I become better thinker and knowledgeable.
I think more about calories before I eat anything ;
and I put in mind that even decimal calories add
up together for all the food that I eat.
I make better decisions in choosing food with
low calories.
I communicate with my friends and find out what
activities burn more calories.
