Step 1I'll solve this problem step by step, using precise estimates and LaTeX formatting:
Step 2: Estimate Gas Mileage
- Typical car gets around $$25 \text{ miles/gallon}
- Inverse of this is \frac{1}{25} = 0.04 \text{ gallons/mile}
Final Answer
- Gas Mileage: 25 \text{ miles/gallon} - Gallons per Mile: 0.04 \text{ gallons/mile} - Energy per Mile: 5.2 \times 10^{6} \text{ joules/mile} - Heartbeats to Drive 1 Mile: 5.2 \times 10^{6} \text{ heartbeats}
