If a person weighing 120 lbs burns 410 calories per hour while bicycling at 12 mi/h, at what rate would calories be burned?
There appears to be too little information here.
eg. How many calories would a person weighing 150 lbs burn biking at 18 mph?
How many calories would a person weighing 120 lbs burn biking at 10 mph?
