Question: How many Km or miles must a average teenager do on a bike to lose 125g .?
Answers:
3500kcal = 1lb(fat)
125g = .275lb
125g= 962.5kcal
a 130lb person burns about 20.0kcal/km riding
a 155lb person burns about 23.8kcal/km riding
a 190lb person burns about 29.2kcal/km riding
So a 130lb person would have to bike 962/20= 48.1km to burn 125g of fat.
You can use linear interpolation to determine the exact amount you burn per km by exact weight. Ex:
140lb person burns 20+(155-140)*(23.8-20.0)/(155-130)=
22.28kcal/km riding
do the same math to get 962/22.28= 43.2km
