Explanation / Answer

1 calorie per second = 4.1868 watts.

41) running consumes 100 calories per mile. The person runs 10-minute miles for one hour i.e. 6 miles.

Therefore, total calories burned in 1 hour = 6 x 100 = 600 calories.

Calories burned per second = 600/3600 = 0.1667 calories per second.

Therefore power output in watts = 0.1667 x 4.1868 = 0.6978 watts. (Ans.)

42.) while riding a bike, calories are burned at a rate of 50 calories per mile. And the person rides at a speed of 15 miles per hour.

Therefore, calories burned per hour = 50 x 15 = 750 calories per hour.

Calories burned per second = 750/3600 = 0.2083 calories per second.

Power output in watts = 0.2083 x 4.1868 = 0.8722 watts (Ans.)
