Question

A single serving bag of snack chips contains 65.0 Cal. Assuming that all of the energy from eating these chips goes toward keeping your heart beating, how many hours can these chips sustain a heartbeat of 73 beats per minute?

Answer 1

Answer:

= 62.1 hours

Explanation:

Energy provide by the serving is 65 cal

= 65 cal  × 4.184 Kj = 271.96 kJ

271.96 KJ = 271960 J

Energy required for 1minute of energy

= 73 x 1

= 73 J/min

So, 271960 joules will be required for 271960 heart beat

Minutes = 271960 / 73

= 3593.94 minutes  

Time in hours = 3725.429 / 60

= 62.1 hours
