Given: Marcel burns 7.68 cal/s while running
To find: Calories burned by him in Kcal/min
Method: Conversion of cal to kcal by dividing the given number with 1000 and seconds to minutes by dividing the numerator by 60.
Solution:
Calories burned by Marcel while running in calories per second = 7.68 cal/s
Calories burned by Marcel while running in kilo calories per minute = [tex]\frac{7.68}{1000\times60}[/tex] = 0.000128
Hence Marcel burns 0.000128 Kcal/min while running.
