Calories burned by 65 kg runner
• For 1 km
Calories = 1km x 65 kg x 1.036 = 67.34
• For 2 km
Calories = 2km x 65 kg x 1.036 = 134.68
• For 3 km
Calories = 3km x 65 kg x 1.036 = 202.02
Conclusion
• A Krispy Kreme original glazed has 200 calories
• A 65 kg person will burn approximately 202
calories by running 3 km
• So a 65 kg person will have to run about 3 km

Question 1
• How does someone work out the number of
calories they burn when running?
• We work it out by using the formula
Calories = kilometers x kilograms x 1.036
Question 2
• How far would they have to run to burn the
calories that are in a donut? How did you
work it out?
• I used the example of a 65 kg person and used
the formula to calculate the calories burned
for 1 km, 2 km, and 3 km. We multiplied the
distance by the weight by 1.036.
Question 3
• How can knowing how to do arithmetic with
decimals help you make good health
decisions?
• It is important to understand decimals to do
the calculations in our formula. If you do not
know decimals, then you cannot do the
calculations. It was helpful to know the
calories burned in this example.
Question 4
• Which part of the Learner Profile did you
develop in this unit?
• I have learned that exercise is important to
help burn off calories. A balanced diet and
exercise would be healthy for your body.
