Verified step by step guidance

1. Step 1: Understand the problem by identifying the key question: How many times does the average human heart beat in one day?
2. Step 2: Recall the average heart rate for a human, which is approximately 60 to 100 beats per minute under normal conditions.
3. Step 3: Calculate the number of heartbeats per hour by multiplying the average beats per minute by the number of minutes in an hour (60). Use the formula: $\mathrm{Heartbeats}=\mathrm{Beats}/\mathrm{Minute}\times 60$
4. Step 4: Determine the total number of heartbeats in one day by multiplying the heartbeats per hour by the number of hours in a day (24). Use the formula: $\mathrm{Heartbeats}=\mathrm{Beats}/\mathrm{Hour}\times 24$
5. Step 5: Compare the calculated value to the provided answer choices to identify the closest match.
