HOW FAR WOULD
YOU RUN FOR A
DOUGHNUT?
By: Bushra Shaikh
HOW MANY CALORIES ARE THERE IN A
DOUGHNUT?
In these years people have got into a habit of eating junk food all the
time. One of most usual foods is doughnut, did you know that in and
average doughnut there is about 200 calories, in a cream or jam filled
doughnut there is about 300 calories!!!
HOW DO YOU WORK OUT THE NUMBER OF
CALORIES YOU BURN WHEN YOU RUN?
To work out the number of calories you burn when you run is simple. All you have
to do is follow a simple formula. To make this easy keep record of your current
weight before you run and the distance that you run, make sure it is in
kilometers, also that the weight is in kilograms. This is the formula which will
help you to calculate the amount of calories you burn when you run: Calories=
Kilometers x Kilograms x 1.036.
So if Jessica had a weight of 83km( kilograms ) and she ran 5.5 km ( kilometers )
you would take the weight which is 83kg and multiply it by the distance she ran
which 5.5km. Next you multiply it by 1.036 so:
1
1
8 3km
x 5.5kg
41.5
415.0
456.5

1 3
1.036
x 415

5.180
10.360
414.400
429.940
So the
amount of
calories
Jessica burnt
when she ran
is 429.94
calories
EXAMPLE
Laura went for a run this morning she wants to know how many
calories she has burnt. She weighs 57kg and ran 4.6km. So I take the
57kg, multiply it by 4.6km. Next I take the result and multiply it by
1.036:

271.6392
So Laura burnt
271.6392 calories
today.
HOW FAR WOULD WOULD YOU HAVE TO RUN TO
BURN THE CALORIES OF A DOUGHNUT?
If you ate an average doughnut with 200 calories and you wanted to find
out how much distance you have to run to burn that much calorie. Thing
you need to do is this you have to find out how much kilograms you weigh.
So if you weigh 45 kilograms then you have to find out how many calories
you can loose in one kilometer. After you find out try to divide it by 200
then take the result, that is the distance you need to run in order to loose
the amount of calories equal to the calories in a doughnut. If there are
remainders then you can try decimals like 25meters so it will be for
1
example you need to run7.25 km.

So to burn
200 calories
you need to
run 4.2 km.
MAKING YOUR ANSWER REASONABLE
After getting the results you have to make them reasonable so the results
don’t have too many decimal places which will make the answer
unreasonable. To make the result reasonable you have to round up to the
nearest whole number so if it is something like 346.5875Calories
4 then you round it according to the hundredths which will make it 346.6
because 8 is greater than 5, anything which 5 or greater than 5 is rounded
up and less than is rounded down. If you want to be more specific then you
should round it to the nearest hundredths so it becomes 346.59 because after
the 8 there is a 7 so you round up. If you just want to round it to a whole
number then round the tenth to the nearest whole number, in this case it
will be 367 because the tenth is a 5 which means you round up.

HOW CAN KNOWING TO DO ARITHMETIC
WITH DECIMALS HELP YOU TO MAKE GOOD
HEALTH DECISIONS?
Knowing how to do arithmetic with decimals can help me with health
decisions by:
❉When I need to calculate how much I need to run every day to loose
some calories by the end of the week, if know the arithmetic with
decimals properly hen I can easily estimate how many kilometers I need
to run everyday so I can loose enough calories in the end of the week.
❉I don’t have to go to professionals all the time I can figure out by myself
how much exercise I need to do.
❉I’ll know better about what food will not spoil my health by adding up
the calories of all the food that I am eating and make sure I don’t end up
eating too much calories.
❉Arithmetic with decimals will also help me if I ran for example 8.7
kilometers and I want to calculate how many calories I burnt it I’ll be
easier for me because I will know that to do right away.
❉Arithmetic with decimals will also help me be more
confident in my social life because if I can calculate the
amount of calories I burn when I run and at the same
time add up the calories in the food I eat then I wont be
very unhealthy or obese. This will lead to more confidence
I the outer society and I will be able to communicate
better with the community.
❉Another reason is that I will be able to help other
people with my tips and tricks that I learned by using the
arithmetic with decimals.
THINKER
Within this unit I developed my thinking
skills by learning how to figure things in the
right order like the investigations and also
improved my multiplication skills. During
this unit I also learned how to calculate the
calories using a formula and also arithmetic
with decimals.
INQUIRER
I developed my inquiring skills by
investigating how much distance a person
has to run to burn the calories that are
equal to the calories in a doughnut. As well
as when finding out the process of how to
figure out the distance that they need to
run since there could be decimals involved
too.
REFLECTIVE
I reflect on what I have done well and what I
have to improve on. For example when I make
silly mistakes I try to concentrate more on the
question as I reflect on it before I do another
piece of work which is similar or is related.
KNOWLEDGEABLE
I had good understanding of what to do to
solve the problem and I knew how to figure
out how to figure the order of the step. For
example when to multiply with which one of
the numbers or sections and knew what I had
to do next.
BALANCED
I though about how to answer the problem but also
how what I have learned will help me in my personal
life and other people. Like with the calories
investigation instead going to professionals and
finding out how much calories you have or need to
loose you can calculate by yourself. So all this refers
to learning how to understand and do math
investigations and also use what we have learned in
our social and personal lives.
THANK YOU VERY MUCH FOR
