A single serving of Granny Goose Hawaiian Style Potato Chips has 70 Calories. Assuming that all of the energy from eating these chips goes toward keeping your heart beating, how long can these chips sustain a heartbeat of 80 beats per minute? NOTE: 1kcal ( kilocalorie)= 4.184 kJ (kilojoule) and each human heart beat requires 1 J (joule) of energy.

70 Calories = 70 kcal = 292.88 kJ = 292,880 J
292,880 / 80 = 3661 minutes = 61 hours 1 minute

Here's one possible strategy:
Convert 70 Calories into joule (1 Calorie = 1 kcal) => x J
Use heart rate to calculate the number of minutes that correspond to x J (1 heartbeat ~ 1 J)

If a single serving has 70 calories (0.07 kilocalories), then that represents 292 heart beats. or 3.6 minutes. However, I have to warn you that 1 food Calorie is 1000 energy calories.
