Final answer:
It would take approximately 90 heart contractions to drive a car 1 mile.
Step-by-step explanation:
The estimated number of human heartbeats it would take to drive a car 1 mile can be calculated by considering the average rate of heart contraction and the speed of the car.
According to the given information, a human heart contracts approximately 75 times per minute. Assuming an average lifespan of 75 years, the total number of heartbeats in a lifetime would be:
75 contractions/minute × 60 minutes/hour × 24 hours/day × 365 days/year × 75 years = 1,962,000,000 contractions
Now, to estimate how many heart contractions it would take to drive a car 1 mile, we need to consider the speed of the car. Let's assume the car is driving at a constant speed of 50 mph:
- In one hour, the car would travel 50 miles.
- In one minute, the car would travel 50 miles ÷ 60 minutes = 0.8333 miles.
- Therefore, to drive 1 mile, the car would take approximately 1 ÷ 0.8333 minutes = 1.2 minutes.
Since the car takes 1.2 minutes to drive 1 mile and the heart contracts 75 times per minute, the estimated number of heartbeats it would take to drive 1 mile is:
1.2 minutes × 75 contractions/minute = 90 contractions
Therefore, it would take approximately 90 contractions to drive a car 1 mile.
