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
