Question

a single serving bag of snack chips contains 67.0 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 79 beats per minute? note: 1 cal

Answer 1

The chips can sustain a heartbeat of 79 beats per minute for approximately 0.014 hours.

Step-by-step explanation:

To calculate how long the snack chips can sustain a heartbeat, we need to determine the amount of energy provided by the chips and the energy expended by the heart.

The snack chips contain 67.0 calories. However, we need to convert calories to kilocalories (kcal) by dividing by 1000: 67.0 calories = 67.0 kcal.

We also need to determine the energy expended by the heart.

Given that the heart beats at a rate of 79 beats per minute, we can calculate the energy expended per minute by multiplying the heart rate (79 beats/min) by the energy expended per beat.

Since all the energy goes towards keeping the heart beating, we can assume that each beat requires 1 kcal. So, the energy expended per minute is 79 kcal.

To find the number of hours that the chips can sustain the heartbeat, we divide the total energy provided by the chips (67.0 kcal) by the energy expended per minute (79 kcal/min). This gives us approximately 0.848 minutes.

Therefore, the chips can sustain a heartbeat of 79 beats per minute for approximately 0.848 minutes, which is equivalent to about 0.014 hours.
